SUMMARY:Intrication quantique dans les systèmes de particules identiques : bases et applications. -(Christian Schilling / LPT / Seminar). - 3/11/2025\, 11H
DESCRIPTION:Séminaire LPT \nChristian Schilling (Centre Sommerfeld de physique théorique\, LMU Munich) \nSeminar LPT\, 3/11/2025\, 11H\, 3R4\, salle de conférence \nSummary \nEntanglement is a fundamental feature of the quantum world and a key resource for quantum information processing. While the concept of entanglement for distinguishable particles is well established\, its validity for identical particles remains a subject of debate and misconceptions. In this talk\, we resolve this foundational issue: We demonstrate that identical particles do not form proper subsystems\, rendering the concept of entanglement inapplicable to identical particles in first quantization. However\, in second quantization\, where the focus shifts from particles to the inherently distinguishable orbitals\, entanglement becomes well-defined. We then systematically apply this perspective to physics and chemistry. In particular\, we show how quantum phase transitions manifest within this framework and how it provides a deeper understanding of chemical bonding. Furthermore\, we propose a systematic approach to enhancing wave function methods for strongly correlated electron systems\, relevant to both classical and quantum computing. Altogether\, these insights highlight the deep connection between quantum information and many-body physics\, demonstrating fruitful synergies that can foster the second quantum revolution.\n\n[1] D.Aliverti-Piuri\, J.Liebert\, C.Schilling\, forthcoming\n[2] D.Aliverti-Piuri\, K.Chatterjee\, L.Ding\, K.Liao\, J.Liebert\, C.Schilling\, Faraday Discuss. 254\, 76 (2024)\n[3] K.Liao\, L.Ding\, C.Schilling\, J.

SUMMARY:Réseaux de tenseurs pour la résolution d’EDP multi-échelles. -(Jheng-Wei Li / LPT / Seminar). - 4/11/2025\, 14H
DESCRIPTION:Séminaire LPT \nJheng-Wei Li (CEA) \nSeminar LPT\, 4/11/2025\, 14H\, 3R4\, salle de conférence \nSummary \nMany problems in science and engineering are described by partial differential equations (PDEs). Examples range from neutron diffusion in nuclear reactors to electron motion on superlattices. These equations are hard to solve in practice because they involve many different length scales that render conventional discretization approaches prohibitively costly. \nIn this talk\, I will show how ideas from many-body physics\, in particular tensor networks\, can overcome this difficulty. Tensor networks are clever ways of compressing large\, structured data without losing essential information. Originally invented to describe quantum many-body wavefunctions\, they can also be adapted to PDEs. I will use two simple\, instructive examples to illustrate how to accomplish this. \nThe key message is that « exponentially many » variables do not necessarily imply « exponentially hard » computations. By bridging concepts from many-body physics and functions of continuous variables\, tensor networks give a promising pathway toward a scalable approach for multi-scale PDEs and beyond. \n\n\n\n

SUMMARY:When electrons and photons meet molecules: measurements\, mechanisms\, and implications. - (Ana Isabel Lozano / LCAR / Seminar). - 6/11/2025\, 11H
DESCRIPTION:Séminaire LCAR \nAna Isabel Lozano\, IRAP Université de Toulouse \nSummary\nIn this seminar\, I will cover the two main axes of my research: electron-molecule collisions and photophysics of gas-phase molecules. In the first part of the talk\, I will present recent results obtained with the PIRENEA setup\, which allows us to distinguish between isomeric cationic species and to identify the products arising from ion-molecule reactions. In the second part of the talk\, I will describe a state-of-the-art experimental setup designed to measure electron scattering cross sections\, and I will discuss how combining cross section measurements with the characterization of transient negative ions contributes to advancing our understanding of electron-induced processes. Finally\, I will share some exciting perspectives concerning electron-molecule collision experiments.

SUMMARY:Quantum Thermalization via Travelling Waves. -(Antonio Picano /  LPT / Seminar). - 12/11/2025\, 14H
DESCRIPTION:Séminaire LPT \nAntonio Picano (Collège de France) \nSeminar LPT\, 12/11/2025\, 14H\, 3R4\, salle de conférence \nSummary\nIsolated quantum many-body systems which thermalize under their own dynamics are expected to act as their own thermal baths [1]\, thereby losing memory of initial conditions and bringing their local subsystems to thermal equilibrium. Here [2]\, we show that the infinite-dimensional limit of a quantum lattice model\, as described by dynamical mean-field theory (DMFT)\, provides a natural framework to understand this self-consistent thermalization process [3\, 4]. Using the Fermi-Hubbard model as a working example\, we demonstrate that the emergence of a self-consistent bath occurs via a sharp thermalization front\, moving ballistically and separating the initial condition from the long time thermal fixed point (Fig. 1). We characterize the full DMFT dynamics through an effective temperature for which we derive a traveling wave equation of the Fisher-Kolmogorov-Petrovsky-Piskunov type [5]. This equation allows for predicting the asymptotic shape of the front and its velocity\, which match perfectly the full DMFT numerics. Our results provide a new angle to understand the onset of quantum thermalization in closed isolated systems. \nA natural avenue for future applications of this methodology is the case of disordered quantum many-body systems\, using statistical DMFT [6]. We can expect that\, in an Anderson localized phase\, the ballistic front would give way to a localized one\, which never loses memory of the initial condition. In the presence of disorder and interactions\, we argue a competition between thermalizing fronts and pinning due to disorder\, which could shed new light on the stability of many-body localization. \nReferences \n[1] R.

SUMMARY:Un piano sonne-t-il différemment selon les pianistes ?. - (Juliette CHABASSIER / Seminar/ SFP). - 14/11/2025\, 11H
DESCRIPTION:Séminaire SFP \nJuliette CHABASSIER\, INRIA Bordeaux Sud Ouest\, Salle de Conférence\, Bât. 3R4\nRésumé:\nL’acoustique musicale cherche à objectiver les observations et les ressentis des musiciens et des fabricants d’instruments de musique\, afin de rationaliser les procédés de fabrication et le jeu musical. Dans ce contexte\, la simulation numérique apporte une contribution précieuse en permettant de réaliser des scenarios bien contrôlés\, et en mettant à l’épreuve les modèles issus de notre compréhension du fonctionnement des instruments de musique. Cet exposé s’intéresse au piano\, et plus précisément à la question du toucher pianistique. Les fabricants apportent en effet un soin tout particulier à la réalisation de la mécanique mettant en relation le musicien avec le marteau qui ensuite frappe les cordes\, et les musiciens développent une technique très precise dans leur façon d’enfoncer les touches\, pour contrôler cette mécanique. Cependant\, les effets réels de cette trajectoire sur le son du piano font l’objet d’une controverse. Grâce à un modèle vibro-acoustique de piano complet (de la touche au son produit)\, ainsi qu’une stratégie de discrétisation originale et efficace\, nous sommes en mesure de simuler des sons obtenus à partir de touchers réels mesurés sur un piano équipé. \nDans cet exposé\, nous aborderons tout d’abord quelques stratégies numériques originales\, dites quadratisées\, s’attaquant aux aspects non linéaires présents dans les instruments de musique comme le piano\, en montrant leurs effets sonores inattendus. \nEn deuxième partie nous présenterons des résultats de simulation : toutes choses étant égales par ailleurs\, l’effet de l’enfoncement de la touche de piano sur le son produit pourra être quantifié et objectivé. \nAffiche presentation séminaire SFP\,Juliette CHABASSIER

SUMMARY:Simulation de systèmes quantiques à plusieurs corps. - (Olivier Simard / LPT / Seminar). - 20/11/2025\, 14H
DESCRIPTION:Séminaire LPT \nOlivier Simard (École Polytechnique) \nSeminar LPT\, 20/11/2025\, 14H\, 3R4\, salle de conférence \nSummary\nA significant part of the condensed matter community has been devoted to understanding and modelling strongly correlated quantum materials. To tackle the complexity of quantum many-body problems\, a wide array of « classical » computational methods has been developed [1-3]. Paradigmatic models such as the Hubbard model (and its extensions) or the transverse-field Ising model—despite their apparent simplicity—have sparked extensive computational investigations in both equilibrium and nonequilibrium settings. In recent years\, progress in algorithms and increasing classical computational power have led to a convergence of state-of-the-art methods\, which now begin to agree within their overlapping regimes of applicability [4-6]. Yet\, quantum systems exhibiting long-range entanglement at low temperatures remain especially challenging for classical numerical approaches. An alternative route is provided by synthetic quantum simulators: experimental platforms governed by quantum mechanics that implement target Hamiltonians [7-9]. These include cold atoms in magneto-optical lattices and superconducting circuits. Among them\, cold atom platforms stand out for their flexibility in realizing diverse systems and finely tuning microscopic interactions\, achieving temperatures low enough to explore exotic phenomena such as unconventional superconductivity [10]. However\, current quantum simulators still suffer from imperfections and noise [11-13]\, and many relevant quantum systems have yet to be mapped onto these platforms. In this seminar\, I will present several classes of classical numerical methods designed to address quantum many-body problems in and out of equilibrium\, outlining their advantages and limitations. I will also introduce some quantum simulation architectures and the challenges they face\, and share ideas I have developed with collaborators to overcome these hurdles and enhance their capabilities. \n[1-3] PhysRevB.43.5950\, RevModPhys.68.13\, RevModPhys.90.025003\n[4-6] PhysRevX.13.011007\, PhysRevX.11.041013\, PhysRevX.11.011058\n[7-9] PRXQuantum.2.017003\, Nature Physics 8\, 267–276\, RevModPhys.80.885\n[10] arXiv.2502.00095\n[11-13] RevModPhys.87.637\, PhysRevA.97.053803\, J.

SUMMARY:Evolution of chemical and physical transformations under electron beams\, light\, and mechanical impact. - (Dominik Lungerich / CEMES / Seminar). - 21/11/2025\, 11 H
DESCRIPTION:Séminaire du CEMES \nDominik Lungerich\, CEMES  \nSeminar CEMES\, 21/11/2025\, 11H \nSummary\nThe advent of aberration-corrected transmission electron microscopy (AC-TEM) has revolutionized materials science and adjacent disciplines\, enabling researchers to capture atomic-level details with unprecedented precision. Among these developments\, single-molecule atomic-resolution time-resolved electron microscopy (SMART-EM) has emerged as a powerful approach to visualize dynamic events at the molecular and atomic scale in real time. \nMy research integrates these microscopic insights with chemical understanding—through the lens of an organic chemist—to elucidate reaction mechanisms driven by electron beams.[1–5] Using high-resolution imaging\, complemented by image simulations and density functional theory calculations\, we demonstrate the controlled formation of carbon nanostructures at the molecular level. These results establish electron-beam chemistry as a distinct and complementary approach to conventional thermal\, photochemical\, and mechanochemical methods. \nUsing light as an energy source\, I investigate molecular photoswitches as building blocks for responsive and mechanically active materials.[6] Among them\, azobenzenes—undergoing a pronounced geometrical change from ~1 nm (trans) to ~0.5 nm (cis)—represent some of the most promising actuators. Inspired by biological muscle systems\, we tailor their response through dopants and environmental modulation\, creating complex multiresponsive materials that can be triggered by stimuli beyond light alone. \nFinally\, mechanochemically assisted synthesis continues to gain importance in both academia and industry but remains limited by an incomplete understanding of reaction kinetics. In particular\, dependencies on the type and dynamics of milling equipment are poorly understood and often overlooked. To address this\, I identify critical kinetic parameters using kinematic models\, enabling reproducibility and cross-comparison of mechanochemical reactions across commonly used planetary and mixer mills.[7] \nTogether\, these studies illustrate how directed energy inputs—electronic\, photonic\, and mechanical—can drive and control chemical transformations with spatial and temporal precision\, expanding the boundaries of molecular design and materials engineering. \nReferences: \n\n[1] J.-Y.

SUMMARY:La morphologie comme lecture de l’état cellulaire : classification\, métriques et dynamiques. - (Ashok Prasad / LPT / Seminar). - 25/11/2025\, 14H
DESCRIPTION:Séminaire LPT \nAshok Prasad (Université d’État du Colorado) \nSeminar LPT\, 25/11/2025\, 14H\, 3R4\, salle de conférence \nSummary\nCell morphology offers a powerful and underutilized lens for understanding cellular identity\, behavior\, and state. While transcriptomic and proteomic profiling have revolutionized our capacity to characterize cells\, quantitative morphological features can provide complementary insights into cell state and function. In this talk\, I will present our recent work demonstrating that cells can be robustly classified using a range of morphological metrics derived from microscopy images. I will discuss our ongoing efforts for deeper insight. These include studying the relationship between cell shape\, actin structure and nuclear size and shape as well as by developing new morphological measures that are sensitive to the structure and dynamics of intracellular structures\, especially the actin cytoskeleton and other dynamic biopolymer networks. We simulate the actin cytoskeleton\, incorporating the action of molecular motors and cross-linkers\, and look for features that are sensitive to different initial conditions and differences in temporal dynamics. Ultimately\, we seek to build a framework in which cellular morphology is treated as a high-dimensional\, information-rich signature of cell state. Our work is part of a broader vision of morphology-based phenotyping as a bridge between structure and function in living systems.

SUMMARY:Towards control of quantum materials using intense laser pulses. - (Nicolas TANCOGNE-DEJEAN / FeRMI / Séminaire). - 25/11/2025\, 11H
DESCRIPTION:Séminaire FeRMI \nNicolas TANCOGNE-DEJEAN\,  Research Center Futur Energy Materials and Systems of the University Alliance Ruhr and Interdisciplinary Centre for Advanced Materials Simulations (Ruhr University Bochum\, Allemagne) \nSummary :\nAll-optical spectroscopy of matter is a well established technique to access properties of electrons and quasi-particles in matter\, and the description of optical properties of material is well understood in the limit of weak laser fields. Recent advances in experimental techniques have opened up the possibility to develop novel types of spectroscopies based ultrashort and intense laser pulses.\nUsing these new probes allows for instance to access non-equilibrium dynamics of condensed-matter systems\, coherently control magnetization on ultrafast timescales\, or to allow for exploring non-equilibrium phase diagram of correlated materials.\nThe strong-field electronic dynamics in solids have received a lot of attention\, in particular due to the experimental observation of high-harmonic generation in solids. The dynamics associated with strong laser fields requires a non-perturbative description of the electronic dynamics. In this talk\, I will present how a successful way for describing this strong-field dynamics in quantum materials\, using ab initio methods based on real-time time-dependent density functional theory\, complemented by an ab initio Hubbard U [1].\nI will present some examples of how these intense lasers can be used to coherently control materials’ properties\, in particular correlated materials electronic structure [2]\, magnetic [3]\, and optical properties on ultrafast timescales [4\,5]\, especially focusing on recent experimental validations of the earlier theoretical predictions. \n[1] .
