Scaling of temporal entanglement in proximity to integrability
Alessio Lerose, Michael Sonner, Dmitry A. Abanin
Describing dynamics of quantum many-body systems is a formidable challenge due to rapid generation of quantum entanglement between remote degrees of freedom. A promising approach t…

Influence functional of many-body systems: temporal entanglement and matrix-product state representation
Michael Sonner, Alessio Lerose, Dmitry A. Abanin
Feynman-Vernon influence functional (IF) was originally introduced to describe the effect of a quantum environment on the dynamics of an open quantum system. We apply the IF approa…
