Nonequilibrium boundary-driven quantum systems: Models, methods, and properties

GT Landi, D Poletti, G Schaller - Reviews of Modern Physics, 2022 - APS
Recent years have seen tremendous progress in the theoretical understanding of quantum
systems driven dissipatively by coupling to different baths at their edges. This was possible …

Bose-Hubbard triangular ladder in an artificial gauge field

CM Halati, T Giamarchi - Physical Review Research, 2023 - APS
We consider interacting bosonic particles on a two-leg triangular ladder in the presence of
an artificial gauge field. We employ density matrix renormalization group numerical …

Effect of order of transfer matrix exceptional points on transport at band edges

M Saha, BK Agarwalla, M Kulkarni… - arXiv preprint arXiv …, 2024 - arxiv.org
Recently, it has been shown that, in one dimensional fermionic systems, close to band
edges, the zero temperature conductance scales as $1/N^ 2$, where $ N $ is the system …

[HTML][HTML] Nonequilibrium quantum dynamics and chiral Bloch oscillation in an interacting two-leg ladder induced by defect perturbations

Y Jian, AX Zhang, ZF Yu, JK Xue - Physics Letters A, 2024 - Elsevier
The nonequilibrium quantum dynamics and nonlinear chiral Bloch oscillation in interacting
flux ladder induced by arbitrarily distributed defects are studied analytically and numerically …

Robust nonequilibrium edge currents with and without band topology

MT Mitchison, Á Rivas, MA Martin-Delgado - Physical Review Letters, 2022 - APS
We study two-dimensional bosonic and fermionic lattice systems under nonequilibrium
conditions corresponding to a sharp gradient of temperature imposed by two thermal baths …

Robust nonequilibrium surface currents in the three-dimensional Hofstadter model

MT Mitchison, Á Rivas, MA Martin-Delgado - Physical Review Research, 2022 - APS
Genuinely two-dimensional robust crosscurrents—which flow against the natural direction of
heat flux—have been missing since the discovery of their one-dimensional counterpart. We …

Thermopower in a boundary-driven bosonic ladder in the presence of a gauge field

B Xing, X Xu, V Balachandran, D Poletti - Physical Review B, 2022 - APS
We consider a bosonic two-legged ladder whose two-band energy spectrum can be tuned in
the presence of a uniform gauge field, to four distinct scenarios: degenerate or …
