Quantum tunneling dynamics in a complex-valued Sachdev-Ye-Kitaev model quench-coupled to a cool bath
Y. Cheipesh, A. I. Pavlov, V. Ohanesjan +2
The Sachdev-Ye-Kitaev (SYK) model describes interacting fermionic zero modes in zero spatial dimensions, e.g. quantum dot, with interactions strong enough to completely washout qua…

Entanglement correction due to local interactions in many-body systems
Yevheniia Cheipesh, Lorenzo Cevolani, Stefan Kehrein
The correction to the area law for the bipartite min-entanglement entropy of weakly and locally interacting fermions is calculated based on a perturbative extension of the flow equ…
