Description
Recently current fluctuations of a class of models have been shown to be described by the so called M-Wright function, which takes the form of nested Gaussian. This was first noted for a classical automaton model, but has been discussed to appear in a wide class of models including the XXZ spin chain. In this talk we explain how the distribution can be derived by an exact calculation for the so-called t0 model, which is the Hubbard model with infinite strength of interaction. The talk is based on a collaboration with K. Fujimoto, T. Ishiyama, T. Kurose, T. Yoshimura.
