CoRR, 2022 - 〔Major achievements〕An eikonal equation approach to thermodynamics and the gradient flows in information geometry
TatsuakiWada; Antonio M. Scarfone; Hiroshi Matsuzoe, Lead, We can incorporate a “time” evolution into thermodynamics as a Hamilton–Jacobi dynamics. A set of the equations of state in thermodynamics is considered as the generalized eikonal equation, which is equivalent to Hamilton–Jacobi equation. We relate the Hamilton–Jacobi dynamics of a simple thermodynamic system to the gradient flows in information geometry., Elsevier

CoRR, 2021 - A study of Rényi entropy based on the information geometry formalism
Antonio M Scarfone; Hiroshi Matsuzoe; Tatsuaki Wada, Last, In the framework of information geometry, we explore the structure of statistical manifold related to the Rényi entropy. Starting from a new family of generalized exponential distributions given by the equilibrium distribution of a canonical system described by the Rényi entropy, we introduce on a dually-flat geometry endowed by a Hessian structure derived from a generalization of the Fisher metric and a flat affine connection. This geometrical structure admits a Legendre transform that links the thermodynamic potentials of the underlying statistical mechanics to the dual potentials of the corresponding information geometry. A canonical divergence function à la Bregman is naturally derived in this framework. Further geometric structures, derived from other contrast functions strictly related to the Rényi entropy are explored and their link with the -geometry of Amari is highlighted., IOP

Entropy, Oct. 2015, [Reviewed], [Invited] - Massless Dirac Equation from Fibonacci Discrete-Time Quantum Walk
Giuseppe Di Molfetta; Lauchlan Honter; Ben B. Luo; Tatsuaki Wada; Yutaka Shikano, Discrete-time quantum walks can be regarded as quantum dynamical simulators since they can simulate spatially discretized Schrödinger, massive Dirac, and Klein–Gordon equations. Here, two different types of Fibonacci discrete-time quantum walks are studied analytically. The first is the Fibonacci coin sequence with a generalized Hadamard coin and demonstrates six-step periodic dynamics. The other model is assumed to have three- or six-step periodic dynamics with the Fibonacci sequence. We analytically show that these models have ballistic transportation properties and continuous limits identical to those of the massless Dirac equation with coin basis change.
