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 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…
