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 …

Anomalous transport from hot quasiparticles in interacting spin chains

S Gopalakrishnan, R Vasseur - Reports on Progress in Physics, 2023 - iopscience.iop.org
Many experimentally relevant quantum spin chains are approximately integrable, and
