Exact anomalous current fluctuations in the strong-anisotropy limit of the XXZ chain
Taiki Ishiyama, Taiga Kurose, Kazuya Fujimoto +1
We study spin-current fluctuations of the folded XXZ chain, which describes the strong-anisotropy limit of the XXZ chain. We obtain an exact expression for the moment-generating fu…

Exact Anomalous Current Fluctuations in Quantum Many-Body Dynamics
Kazuya Fujimoto, Taiki Ishiyama, Taiga Kurose +2
Fluctuations of integrated currents have attracted considerable interest over the past decades in the context of statistical mechanics. Recently, anomalous current fluctuations, ch…
