Non-stationary current fluctuations in 1D boundary-driven diffusive systems via Macroscopic Fluctuation Theory
Daisuke Suzuki, Tomohiro Sasamoto
While Macroscopic Fluctuation Theory (MFT) has been highly successful in analyzing non-equilibrium steady states, its application to non-steady-state processes remains limited. In…
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 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…
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…
Quantum Transport in Interacting Spin Chains: Exact Derivation of the GUE Tracy-Widom Distribution
Kazuya Fujimoto, Tomohiro Sasamoto
We theoretically study quantum spin transport in a one-dimensional folded XXZ model with an alternating domain-wall initial state via the Bethe ansatz technique, exactly demonstrat…
Exact Solution of Bipartite Fluctuations in One-Dimensional Fermions
Kazuya Fujimoto, Tomohiro Sasamoto
Emergence of hydrodynamics in quantum many-body systems has recently garnered growing interest. The recent experiment of ultracold atoms [J. F. Wienand {\it et al.}, Nat. Phys. (20…
