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…
Integral formula for the propagator of the one-dimensional Hubbard model
Taiki Ishiyama, Kazuya Fujimoto, Tomohiro Sasamoto
We present an exact integral formula for the multi-particle propagator of the one-dimensional Fermi--Hubbard model on an infinite lattice. The proof is based on the nested Bethe an…
Exact Current Fluctuations in a Tight-Binding Chain with Dephasing Noise
Taiki Ishiyama, Kazuya Fujimoto, Tomohiro Sasamoto
The full counting statistics (FCS) of current has long provided fundamental insights into nonequilibrium systems. Recently, the FCS in quantum many-body systems has attracted growi…
Exact density profile in a tight-binding chain with dephasing noise
Taiki Ishiyama, Kazuya Fujimoto, Tomohiro Sasamoto
We theoretically investigate the many-body dynamics of a tight-binding chain with dephasing noise on the infinite interval. We obtain the exact solution of an average particle-dens…
