The sampling simulation device by the decisive theory mode which generates multiple distribution simultaneously

摘要

The trajectory of solutions is calculated by numerically integrating deterministic differential equations, and when sampling along this trajectory, it is set in such a way that a distribution obtained by combining a plurality of Tsallis distributions in which the solution of differential equations covers an energy range wider than that of a Boltzmann-Gibbs (BG) distribution can be reproduced. Several values are set to the parameter of the Tsallis distribution, and a distribution is obtained by combining Tsallis distributions each corresponding to a different parameter value. Using sampling points sampled from the trajectory obtained from the distribution obtained by combining a plurality of Tsallis distributions, the physical and chemical characteristics of a physical system according to the BG distribution can be calculated by a method of statistical mechanics.
