Temporal entanglement, quasiparticles and the role of interactions
Giacomo Giudice, Giuliano Giudici, Michael Sonner +4
In quantum many-body dynamics admitting a description in terms of non-interacting quasiparticles, the Feynman-Vernon influence matrix (IM), encoding the effect of the system on the…
Localization of a mobile impurity interacting with an Anderson insulator
Pietro Brighi, Alexios A. Michailidis, Kristina Kirova +2
Thermalizing and localized many-body quantum systems present two distinct dynamical phases of matter. Recently, the fate of a localized system coupled to a thermalizing system view…
Propagation of Many-body Localization in an Anderson Insulator
Pietro Brighi, Alexios A. Michailidis, Dmitry A. Abanin +1
Many-body localization (MBL) is an example of a dynamical phase of matter that avoids thermalization. While the MBL phase is robust to weak local perturbations, the fate of an MBL…
Bilayer WSe as a natural platform for interlayer exciton condensates in the strong coupling limit
Qianhui Shi, En-Min Shih, Daniel Rhodes +8
Exciton condensates (EC) are macroscopic coherent states arising from condensation of electron-hole pairs. Bilayer heterostructures, consisting of two-dimensional electron and hole…
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…
