Exact Anomalous Current Fluctuations in Quantum Many-Body Dynamics

Author(s): Kazuya Fujimoto, Taiki Ishiyama, Taiga Kurose, Takato Yoshimura, and Tomohiro SasamotoFluctuations of integrated currents have attracted considerable interest over the past decades in the context of statistical mechanics. Recently, anomalous current fluctuations, characterized by the M-Wright function, were obtained exactly in a classical automaton [Ž. Krajnik et al., Phys. Rev. Lett…[Phys. Rev.
