Michael Jabbour (Université libre de Bruxelles) Seminar LPT, 16/01/2024, 14H, 3R1, seminar room, 3rd floor Résumé: One of the most basic tasks in information theory is communication. The capacity of a quantum channel is the maximum rate at which information can be transmitted through it reliably (in the asymptotic limit) per use of the channel.… Read More »Resserrement des limites de continuité sur les entropies et des limites sur les capacités quantiques. – (Michael Jabbour / LPT / Seminar). – 16/01/2024, 14 H.

Arnab Das (Indian Association for the Cultivation of Science, Kolkata ) Seminar LPT, 26/02/2024, 11H, 3R4, Conference hall Abstract:: Periodically driven quantum system with several degrees of freedom is naïvely expected to heat up indefinitely leading a locally infinite temperature -like state at long time. A strong exception to this intuitive picture is observed if… Read More »Dynamical Freezing and Emergent Floquet Conservation Laws. – (Arnab Das / LPT / Seminar). – 26/02/2024, 11 H.

Mirjam Weilenmann ((IQOQI, Vienne) Seminar LPT, 27/02/2024, 14H, 3R1, seminar room, 3rd floor Abstract : Self-testing usually refers to the task of taking a given set of observed correlations that are assumed to arise via a process that is accurately described by quantum theory, and trying to infer the quantum state and measurements from this.… Read More »Self-tests of Physical Theories in Networks and Their Implications for the Foundations of Quantum Theory. – (Mirjam Weilenmann/ LPT / Seminar). – 27/02/2024, 14 H.

Keisuke Totsuka (YITP, Kyoto) Seminar LPT, 12/03/2024, 11H, 3R4, Conference hall Summary The Kondo-lattice model and its variants (e.g., the Kondo-Heisenberg model), in which itinerant fermions interact with immobile magnetic moments via spin-exchange coupling (Kondo coupling), have been playing an important role in understanding the physics of heavy-fermion systems. In this talk, I begin by… Read More »Ground-state phases of the one-dimensional SU(N)-symmetric Kondo lattice model. – (Keisuke Totsuka / LPT / Seminar). – 12/03/2024, 11 H.

Marco Tarzia (LPTMC) Seminar LPT, 26/03/2024, 14H, 3R1, seminar room, 3rd floor Abstract : A central theoretical issue at the core of the current research on many-body localization (MBL) consists in characterizing the statistics of rare long-range resonances in many-body eigenstates. This is of paramount importance to understand : (i) the critical properties of the… Read More »Large-deviation analysis of rare resonances for the Many-Body localization transition. – (Marco Tarzia / LPT / Seminar). – 26/03/2024, 14 H.

Frédéric Mila (EPFL) Seminar LPT, 29/03/2024, 11H, 3R1, seminar room, 3rd floor Abstract : The thermal properties of frustrated quantum magnets are a real challenge because, when formulated in the natural configuration basis, Quantum Monte Carlo simulations suffer from a very serious minus sign problem that excludes simulations below temperatures of the order of the… Read More »Propriétés thermiques des aimants quantiques frustrés. – (Frédéric Mila / LPT / Seminar). – 29/03/2024, 11 H.
