SUMMARY:Quantum many-body dynamics and the quest for massive entanglement production. - (Tommaso Roscilde / LPT / Seminar). - 13/01/2026\, 14H
DESCRIPTION:Séminaire LPT \nTommaso Roscilde (EPFL) \nSeminar LPT\, 13/01/2026\, 14H\, 3R4\, salle de conférence \nSummary : \nMany-body quantum entanglement is the fundamental trait which separates our macroscopic world and the microscopic one\, in which Schrödinger’s cats do exist — they are simply too small to meow\, for the moment… Many-body entanglement is also the central resource of long-sought quantum technologies of next generation. Identifying effective ways to produce many-body entanglement over the largest possible scales\, and in the shortest possible times\, is clearly a grand challenge for quantum many-body theory and non-equilibrium quantum statistical mechanics. \nIn this talk I will discuss how turning to long-range interacting systems is a natural choice for effective entanglement production. The onset of large-scale multipartite entanglement corresponds in general to the relaxation of the system towards long-range order; and the latter is typically associated with thermalisation of closed quantum systems. I will show that this point of view\, while valid in some cases — such as the quasi-adiabatic preparation of low-energy states — may not be appropriate for the most effective forms of entanglement dynamics. The latter defy the conventional classification schemes (ergodic vs. non-ergodic) of quantum dynamics\, and suggest a more inclusive classification\, which is already accepted in classical physics. \n\n\n\n
