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…
Thouless Energy Across Many-Body Localization Transition in Floquet Systems
Michael Sonner, Maksym Serbyn, Zlatko Papić +1
The notion of Thouless energy plays a central role in the theory of Anderson localization. We investigate the scaling of Thouless energy across the many-body localization (MBL) tra…
Disorder and interaction in chiral chains: Majoranas vs complex fermions
Jonas F. Karcher, Michael Sonner, Alexander D. Mirlin
We study the low-energy physics of a chain of Majorana fermions in the presence of interaction and disorder, emphasizing the difference between Majoranas and conventional (complex)…
Multifractality of wave functions on a Cayley tree: From root to leaves
M. Sonner, K. S. Tikhonov, A. D. Mirlin
We explore the evolution of wave-function statistics on a finite Bethe lattice (Cayley tree) from the central site ("root") to the boundary ("leaves"). We show that the eigenfuncti…
