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.
