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…
