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

Robust nonequilibrium surface currents in the three-dimensional Hofstadter model
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
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 …
