Density-wave steady-state phase of dissipative ultracold fermions with nearest-neighbor interactions

Abstract

In this work we investigate the effect of local dissipation on the presence of density-wave ordering in spinful fermions with both local and nearest-neighbor interactions as described by the extended Hubbard model. We find density-wave order to be robust against decoherence effects up to a critical point where the system becomes homogeneous with no spatial ordering. Our results will be relevant for future cold-atom experiments using fermions with non-local interactions arising from the dressing by highly-excited Rydberg states, which have finite lifetimes due to spontaneous emission processes. arXiv:1811.07369v1 [cond-mat.quant-gas]

Simulation methods for open quantum many-body systems

“…Initially, effective Lindblad master equations have been used to describe quantum transport in closed quantum systems using DMFT (Arrigoni et al, 2013;Titvinidze et al, 2015Titvinidze et al, , 2016. Recently, this approach has been extended to the case where already the initial many-body problem describes an open quantum system (Panas et al, 2019).…”

A quantum Boltzmann equation for strongly correlated electrons

“…This allows to consistently combine the QBE with non-perturbative methods which have been developed to study true non-equilibrium steady states within DMFT. [37][38][39][40][41][42][43] The paper is organized as follows: In section II, we present the formulation of a non-perturbative QBE which is consistent with non-equilibrium DMFT. In Sec.…”
