SUMMARY:Waveguide quantum electrodynamics with atomic rings around an optical nanofiber.- (Juliette Jiménez Jaimes / LCAR / Thesis). -16/10/2026\, 9 a.m.
DESCRIPTION:PhD defense \nJuliette Jiménez Jaimes LCAR\, Salle de conférence\, Bat. 3R4\, 9 a.m. \nAbstract :\nThis thesis investigates the collective interaction between regular circular atomic arrays and the electromagnetic field of an optical nanofiber. The central question is how the discrete rotational symmetry of the atomic geometry\, combined with the modal structure and long-range propagation of the nanofiber field\, can be used to control both spontaneous emission and scattering of guided photons. For a single atomic ring\, this symmetry produces mode-selective scattering: different fiber guided modes couple to different eigenmodes of the atomic ring and can consequently experience very distinct reflection and transmission spectra at the same optical frequency. For two rings\, an additional exchange parity and the propagation phase accumulated between the rings control the relative coupling of the collective modes of the incident and outgoing fields. Finally\, finite stacks of rings combine the previously mentioned selection rule with longitudinal interference and Bragg-type coherent build-up. They can behave as mode-selective atomic mirrors\, and when two guided modes are assigned to the reflected and transmitted ports\, as prototypes of two-mode photon routers. \n\n \n \n

SUMMARY:From models to real systems: implementation and applications of the multichannel dyson equation.- (Stefano Paggi / LPT / Thesis). -13/10/2026\, 2 p.m.
DESCRIPTION:PhD defense \nStefano Paggi – LPT\, Salle de Conference du Bâtiment 3R4\, 2 p.m. \nAbstract :\nThe multichannel Dyson equation (MCDE) connects many-body Green’s functions via a multichannel many-body self-energy. Two or more many-body Green’s functions can be coupled in the MCDE. Linking one-body and three-body Green’s functions treats satellites and quasiparticles in photoemission on equal footing\, whereas linking two-body and four-body Green’s functions does the same for single and double neutral excitations in optical absorption. Motivated by the exact result of the photoemission spectra of the standard Hubbard dimer\, the work applies the MCDE to the extended Hubbard dimer\, an H$_2$-like model\, which results in an overall better estimation of the photoemission spectrum\, as well as the ground state energy and the HOMO-LUMO gap compared to standard approaches like $GW$ and second Born. We also investigated neutral excitations of a two-level helium-like model using an MCDE coupling two- and four-body Green’s functions. The MCDE returns single and double neutral excitations close to the exact value\, unlike standard approaches like BSE@GW. In order to apply the MCDE to real molecules\, we developed an implementation in a many-body code using \python$ $ and \fortran$ $\, which just needs as input parameters the restricted Hartree-Fock orbital energies\, basis size\, and two-electron repulsion integrals. Using a spin-adapted effective Hamiltonian and Haydock-Lanczos algorithm\, the spectroscopy-specialized code is able to calculate spectra of atoms and molecules. This paves the way for the implementation of the MCDE to other spectroscopies. Currently our group is implementing the MCDE for neutral excitations\, as well as double ionizations. \n\n \n \n

SUMMARY:Fundamental Aspects of Van der Waals Interactions in Physics and Chemistry. - (Peter Szabo / LCPQ / Seminar). - 17/ 09 /2026\, 14H
DESCRIPTION:Séminaire du LCPQ \nPeter Szabo KU Leuven \nSeminar LCPQ\, 15/09/2026\, 14H \nSummary :\nVan der Waals (vdW) interactions arise from electronic zero-point and thermal fluctuations\, scaling rapidly with system size. Despite being weak compared to covalent and ionic bonds\, they are fundamental in determining the structure\, stability\, and spectroscopic properties of molecules and materials. These interactions can be described through linear response functions\, which provide a quantitative framework for understanding and predicting how systems react to small perturbations. Among them polarizability is the most significant\, governing intermolecular interactions and determining spectroscopic observables. Accurate modeling of polarizability is also crucial in developing new methods in density functional theory\, where capturing nonlocal vdW effects remains a major challenge.\nIn our recent study [1]\, we explored the system-size dependence of polarizability\, denoted as α\, within a quantum-mechanical framework. Interestingly\, we found that the general quantum-mechanical system-size dependence of polarizability follows a four-dimensional scaling law\, which deviates from the commonly accepted classical textbook result (classical 3D scaling: α ~ Volume ~ R3\, where R represents the system’s radius). This four-dimensional scaling law is a pure quantum effect arising from quantum fluctuations and remains valid for quantum-mechanical systems with varying spatial dimensions\, symmetry\, and excitation states. Furthermore\, it is also applicable to many-particle systems\, as shown by accurately predicting the dipole polarizability of atoms and small organic molecules. Our unified formula can be extended to arbitrary response functions by renormalizing the quantum fluctuations caused by external perturbations. \nReferences: \n[1] P. Szabo\, et al.\, Phys. Rev.

SUMMARY:Topological phases of the bilinear-biquadratic spin-1 chain with single-ion anisotropy. - (Zakaria Jouini / LPT / Seminar). -16/07/2026\, 11H
DESCRIPTION:Séminaire LPT \nZakaria Jouini (EPFL) \nSeminar LPT\, 16/07/2026\, 11H\, 3R4\, salle de conférence \nSummary \nSince Haldane’s prediction of a finite spin gap in integer-spin chains\, the spin-1 chain has served as a paradigmatic model of quantum magnetism. Beyond the Heisenberg interaction\, the most general SU(2)-invariant model includes a biquadratic interaction\, often completed by an on-site anisotropy\, typical of spin-1 ions in solids. \nIn this talk\, I will present an approach combining bosonization and Bethe ansatz to show that dominant biquadratic interactions in the presence of an on-site anisotropy stabilize a gapped topological phase\, in a region of the phase diagram previously identified by numerical studies as critical with central charge c=2. I will argue that this phase is a new realization of the Haldane phase in the spin-1 chain\, characterized by hidden quadrupolar order\, and I will discuss the prospects and implications for its experimental realization.

SUMMARY:Prediction and Control of Evolving Complex Communities. - (Derviş Can Vural / LPT / Seminar). -7/07/2026\, 14H
DESCRIPTION:Séminaire LPT \nDerviş Can Vural (University of Notre Dame) \nSeminar LPT\, 7/07/2026\, 14H\, 3R4\, salle de conférence \nSummary :\nThe interactions between species in a complex ecological community can be described in terms of simple reaction kinetics: Just like an enzyme turns a substrate into a product\, a goat transforms plant mass into goat mass. However\, unlike ordinary chemical reactions\, the stoichiometry and reaction rates between species can change over time. In this talk I will present the mathematical description of three interesting cases where this happens [1-4]. (1) Evolution: Species adapt to each other: for example\, some plants will evolve to become bitter or poisonous\, in which case a goat may not carry out its transformation as effectively. In turn\, the goat may evolve in response to this change\, say\, producing enzymes that will neutralize the poison. This “evolutionary arms race” will often finalize with an extinction (2) Migration: In some other cases\, one or more new species might migrate and invade a community\, thereby transforming the reaction network. This could happen naturally\, through unintentional human activities\, or intentionally\, via ecological engineering. (3) Fluctuations: The mass transfer stoichiometry between species are often modulated by external factors such as sunlight\, pH\, and temperature: For example\, in a cold year\, a goat has to eat more plant mass before producing a new goat\, since it must spend some of the energy to produce heat. In all three cases\, I will focus on the statistics of species abundances\, and the “first passage statistics” to extinction or some other biologically relevant target.\n[1] V. Nguyen\, D.C.

SUMMARY:The thermal Hall response of the phonon gas - (Kamran Behnia / LNCMI / Seminar). - 2/07/2026\, 14H
DESCRIPTION:Seminar LNCMI \nKamran Behnia\, Laboratoire de Physique et Etude de Matériaux (ESPCI\, Université Paris Sciences & Lettres\, CNRS) \nSeminar LNCMI\, 2/07/2026\, 14H\, LNCMI\, Toulouse \nAbstract\nFirst observed two decades ago [1]\, the phonon Hall effect\, is nowadays observed in numerous insulators\, including non-magnetic ones [2-4].\nThe observation implies a field-induced misalignment between the heat flux and the entropy flux vectors. Phonon thermal Hall conductivity peaks when most phonon-phonon collisions become normal\, indicating a link with phonon hydrodynamics and a magnetic field induced change in the balance of three phonon events.\nThis conjecture is backed by the case of molecular gases subject to magnetic field. In their case\, the Seftleben-Beenakker effect [5] arises due to the field-induced modification of the molecular collision cross sections. The breakdown of the Born-Oppenheimer approximation in a magnetic field can offer a geometric [Berry] phase to ordinary acoustic phonons. A picture\, which would explain the experimentally observed bound to the thermal Hall of elemental insulators [6]. \n[1] C. Strohm\, G. L. J. A. Rikken and P. Wyder\, Phys. Rev.

SUMMARY:Study of the interplay of Magnetism\, Structure\, and Electronic Properties in the Iron-Based superconductor BaFe2S3 - (Yassine Oubaid / LNCMI / Seminar). - 18/06/2026\, 14H
DESCRIPTION:Seminar LNCMI \nYassine Oubaid\, Laboratoire de Physique du Solide at Université Paris Saclay \nSeminar LNCMI\, 18/06/2026\, 14H\, LNCMI\, Toulouse \nAbstract\nRecently\, a family of quasi-one-dimensional Fe-based spin-ladder compounds with the formula BaFe2X3\, where X represents a chalcogen (Se or S)\, has been shown to exhibit superconductivity under pressures exceeding 10 GPa\, with critical temperatures of approximately 10 K or 26 K\, depending on the chalcogen species [1]. \nHowever\, the intriguing properties of these compounds extend far beyond superconductivity. At ambient pressure\, they behave as Mott insulators and display exotic structural and magnetic phenomena\, including multiferroicity near room temperature. As such\, these materials encompass key characteristics of strongly correlated quantum systems. Building on extensive investigations of BaFe2Se3\, this work presents a comprehensive experimental study of BaFe2S3. \nA detailed examination of the structural\, magnetic\, and electronic properties of BaFe2S3 as a function of temperature and pressure was carried out using a multi-technique approach. This included synchrotron X-ray diffraction\, neutron diffraction\, inelastic neutron scattering\, and synchrotron-based infrared spectroscopy\, performed on both powder and single crystals from the same synthesis batch. These experiments enabled the construction of a comprehensive picture of the underlying physics as a function of temperature and pressure. At ambient pressure\, our study revealed novel phases featuring new atomic structures and a previously unreported structural transition to a polar structure\, demonstrating that BaFe2S3 hosts a combination of exotic tilted stripe magnetic order\, multiferroicity\, and magnetoelasticity [2\, 3]. \nUnder pressure\, by combining complementary structural\, magnetic\, optical\, and transport measurements\, we obtained a comprehensive picture of the magnetic and atomic evolution of BaFe2S3. Our results provide evidence for an intriguing dichotomy between localized and itinerant Fe 3d electrons\, which helps explain both the persistence of magnetic order and the emergence of superconductivity. In particular\, we have significantly revised the interpretation of several experimental observations previously reported in the literature\, substantially enhancing our understanding of magnetoelastic coupling\, electronic gap opening\, the insulator-to-metal transition\, structural degrees of freedom\, and superconductivity. \n[1] H. et al.

SUMMARY:Interplay of Amino Acid Sequence\, Intrinsic Folding Propensity\, and Solvent Effects in Shaping Peptide Secondary Structures and their Functional Implications. - ( Aloke Das/ LCAR / Seminar). - 18/06/2026\, 11H
DESCRIPTION:Séminaire LCAR \nAloke Das\, Department of Chemistry\, Indian Institute of Science Education and Research (IISER) Pune\, India \nSummary :\nSecondary structures of peptides play a crucial role in shaping the overall three-dimensional architecture of proteins. The most common secondary structures found in peptides include α- helices\, β-sheets\, and turns. Among these\, turns are especially important because they reverse the direction of polypeptide chains\, thereby contributing to their compactness and stability. Turns are categorized into types such as C7 (γ-turn)\, C10 (β-turn)\, and C13 (α-turn)\, depending on the specific hydrogen-bonded rings formed between residues in the backbone. Given that these structures are fundamentally local\, they can be effectively explored using small\, capped peptides\, which act as minimal models for understanding folding patterns in larger peptides and proteins. Among the twenty naturally occurring amino acids\, glycine (Gly) and proline (Pro) stand out due to their distinct conformational characteristics: glycine\, which lacks a side chain\, is the most flexible\, whereas proline\, featuring a cyclic imino group\, is highly conformationally constrained. Importantly\, the -Pro-Gly- sequence tends to favor a β-turn conformation\, which is commonly found in the loop regions of β-hairpins. \nIn this presentation\, I will discuss our detailed investigation of Pro-Gly containing capped PGX tripeptides (X = A\, L\, V\, I) using a combination of FTIR spectroscopy\, 2D-NMR\, CD\, gas-phase laser spectroscopy\, single-crystal X-ray diffraction (XRD)\, and quantum chemical computations.1-5 Our study shows that PGA and PGL adopt a double β-turn structure across solid\, solution\, and gas phases\, while PGV and PGI prefer an extended β-strand conformation in the solid and solution states but retain a double β-turn structure in the gas phase. These observations emphasize the subtle interplay between the inherent conformational tendencies of amino acid residues\, sequence\, and solvent effects in determining peptide folding motifs. Notably\, the crystallization of these peptides in non-centrosymmetric space groups highlights their potential as functional materials with piezoelectric\, ferroelectric\, and nonlinear optical properties\, thereby linking peptide structural chemistry with materials design.

Specifically\, we seek a model exhibiting complex behavior that cannot be explained by free dynamics\, but which can at the same time be treated exactly. In this talk\, I will describe such a model: the quantum gas of hard rods. I will discuss the computation of its dynamic structure factor and its quench dynamics. Additionally\, I will explore the underlying quantum integrability of the model and its connection to the more renowned Lieb-Liniger model.

DESCRIPTION:Seminar LNCMI \n Revaz Ramazashvili \,LPT \nSeminar LNCMI\, 4/06/2026\, 14H\, Lieu : LNCMI\,Toulouse \nAbstract\nWe predict electric-dipole spin resonance (EDSR) in altermagnetic conductors: in a magnetic field H\, perpendicular to the magnetization\naxis\, an AC electric field will induce spin resonance transitions that\, in sufficiently clean samples\, shall be clearly visible on the ohmic\nbackground. The EDSR signal shall have a lower threshold frequency ω_ = 2H and a 1/√(ω-ω_) divergence above this threshold. \nDisorder cuts off this divergence; the resulting height of the threshold resonance peak shall scale as √(Hτ)\, with τ the relaxation time. \nI also hope to discuss how EDSR can serve as a diagnostic of altermagnetic order in conducting materials and as a means to distinguish it from more familiar\,\nhigher-symmetry forms of Néel order. \nLien Zoom : https://univ-grenoble-alpes-fr.zoom.us/j/94228207316?pwd=khTdznxeFy1ZUYkYftQ0QSox6Fz3iK.1

SUMMARY:Route vers l'observation expérimentale de la multifractalité et universalité KPZ dans la localisation d'Anderson en dimension deux. - (Noam Izem / LPT / These). -02/06/2026\, 14H
DESCRIPTION:Soutenance de thèse \nNoam Izem LPT\, Salle de conférence\, Bat. 3R4 – 14 H \n\nRésumé :\n« La localisation d’Anderson est un phénomène découvert en 1958 par P. W. Anderson dont le principe repose sur les multiples interférences d’une onde cohérente dans un milieu désordonné. Lorsque le désordre est suffisamment fort\, le transport quantique peut être complètement supprimé par ces interférences. Si il existe un grand nombre de résultats exacts en dimension une\, le régime de fort désordre en dimension deux reste difficile d’accès analytiquement. Il existe cependant une approximation dans ce régime\, qui permet de tisser une analogie avec une physique très différente\, l’universalité de Kardar-Parisi-Zhang (KPZ). Dans cette thèse on se propose d’approfondir ce lien en étudiant directement les états propres localisés en dimension deux\, jamais étudiés sous le prisme de l’universalité KPZ. \nUne autre direction de la thèse consiste à proposer une route vers l’observation expérimentale de la multifractalité dans les systèmes d’atomes froids. La multifractalité est une phase intrigante de la matière\, apparaissant notamment à la transition d’Anderson en dimension supérieure à deux\, et est très difficile à observer. Dans cette thèse\, on propose une route pour observer des signatures expérimentales d’une multifractalité contrôlable dans des systèmes d’atomes froids. » \n\n \n \n

I will exemplify the drastic speedups in an unconventional thermodynamic limit of both large number of colors and particles\, and small number of sites. Using a combination of numerical simulations and analytical computation\, we get the exact\, finite and zero temperature\, phase diagrams with systems including several thousand particles.\nIf time allows\, we will discuss generalization of this approach to other Lie groups and models.

It is shown that weak spin-polarized current excites Bloch oscillations of the domain wall angular rotation velocity\, with the oscillation frequency proportional to the current\, modulated by a much higher magnon-range frequency. In addition to that\, the Wannier-Stark localization effects enable controlled switching between different chiral states\, suppressing inertial effects characteristic for the classical regime. \nThe current density required for the chirality manipulation can be significantly lower compared to the classical regime. We also show that for recently discovered novel class of magnetic materials — altermagnets — chirality switching can be driven by the usual (non-spin-polarized)\ncurrent. \n[1] O. Kolezhuk\, R.

SUMMARY:Existing experiments suffice to indirectly verify the quantum essence of gravity. - ( Martin Plavala/ LCAR / Seminar). - 7/05/2026\, 11H
DESCRIPTION:Séminaire LCAR \nMartin Plavala\, Institut für Theoretische Physik\, Leibniz Universität Hannover\, Hannover\, Germany \nSummary\nThe gravity-mediated entanglement experiments employ concepts from quantum information to argue that if entanglement due to gravitational interaction is observed\, then gravity cannot be described by a classical system. However\, the proposed experiments remain beyond out current technological capability\, with optimistic projections placing the experiment outside of short-term future. Here we argue that current matter-wave interferometers are sufficient to indirectly prove that gravitational interaction creates entanglement between two systems. Specifically\, we prove that if we experimentally verify the Schrödinger equation for a single delocalized system interacting gravitationally with an external mass\, then\, under one of two reasonable assumptions\, the time evolution of two delocalized systems will lead to gravity-mediated entanglement.
