Page Curve Entanglement Dynamics of a Gas of Freely Expanding Non-Interacting Fermions

Explore the Page curve entanglement dynamics of a gas of freely expanding non-interacting fermions in this 48-minute conference talk by A. Dahr from ICTS TIFR, presented as part of NCCR SwissMAP's series on effective theories for many-body systems out of equilibrium. Delve into the quantum entanglement evolution and information-theoretic aspects of fermionic systems as they undergo free expansion, examining how entanglement entropy changes over time and its relationship to the Page curve phenomenon. Gain insights into the theoretical framework used to describe non-equilibrium quantum many-body dynamics and understand the fundamental principles governing entanglement in freely evolving fermionic gases.
