José A. Hoyos (Université de São Paulo, Brésil) Abstract : We investigate the effects of impurities on the unitary evolution of an interacting quantum system after a quench. For a large variety of quench protocols, the impurities become locally highly excited while the bulk practically remains in its ground state. As a consequence, the system’s… Read More »Dynamical Griffiths singularities (José A. Hoyos / LPT / Seminar). – 19/04, 14 H.

Jonathan D’Emidio (DIPC, Saint-Sébastien) Abstract : Computing entanglement entropies in strongly interacting many-body systems in two or more dimensions is a notoriously difficult task. Recently, however, a Monte Carlo method based on Jarzynski’s nonequilibrium work equality has enabled highly efficient calculations in quantum spin systems . I will show how this concept can be extended… Read More »Fermionic Entanglement Entropy from Nonequilibrium Work (Jonathan D’Emidio/ LPT / Seminar). – 10/05/2022, 14H

Théo Hennequin (LPT) Abstract : Electrolyte transport through single nanopore is an active field of research since it can be applied to technologies as nanofiltration, or osmotic energies. Carbon Nanotubes (CNT) are among the most promising types of nanopores due to their properties : very clean and hydrophobic surfaces, interesting electrical properties, and a large aspect… Read More »Electrolyte transport through Carbon Nanotubes : a theoretical study (Théo Hennequin / LPT / Seminar). – 17/05/2022, 14H

Dynamic thermalisation hypothesis postulates that a typical isolated many-body system starting from a nonequilibrium state is overwhelmingly likely to reach thermal equilibrium under the action of its internal dynamics.

Ilya Gruzberg (Université d’État de l’Ohio, États-Unis) Summary : Anderson transitions (ATs) between metals and insulators or between topologically distinct insulators, share common features with conventional second-order phase transitions, such as the critical point of the Ising model for a magnet. However, ATs also exhibit many unusual features including the multifractal scaling of the critical… Read More »Anderson transitions and (lost) conformal invariance – (Ilya Gruzberg / Seminar / LPT). – 11/10/2022

Mateo Uldemolins-Nivela (LPS, Orsay)   Summary A magnetic impurity on a conventional superconductor is one of the most simple pair-breaking defects that induces in-gap Yu-Shiba-Rusinov (YSR) bound states, whose intricate spatial structure crucially influences the possibilities of engineering collective impurity states (e.g., Shiba chains, lattices...) and topological superconductivity. In this talk, I will first introduce… Read More »Yu-Shiba-Rusinov states in two-dimensional superconductors. – (Mateo Uldemolins-Nivela / Seminar / LPT). – 08/11/2022

Maxime Rovère (IHRIM, Lyon) Summary While physics has undergone intense upheavals throughout the 20th century, the way philosophers think of human action seems to rely on notions (responsibility, freedom, etc.) most of which do not take into account the new tools of reason. On the contrary, the most common discourses on human actions and emotions… Read More »Chaos et complexité : comment appliquer à l’éthique humaine la rationalité des sciences contemporaines ?- (Maxime Rovère / Seminar / LPT). – 10/11/2022

Grzegorz Rajchel-Mieldzioć (ICFO Barcelone) The negative solution to the famous problem of 36 officers of Euler implies that there are no two orthogonal Latin squares of order six. We show that the problem has a solution, provided the officers can be entangled and construct two quantum orthogonal Latin squares of this size. In other words,… Read More »Brève histoire de l’intrication quantique depuis Euler – (Grzegorz Rajchel-Mieldzioć / Seminar / LPT). – 22/11/2022
