摘要
Provided is a numerical simulation apparatus capable of executing a numerical simulation with high speed and high accuracy by reducing a calculation amount. A numerical simulation apparatus (100) that executes a numerical simulation using a wave function that is a solution of a time-dependent Schroedinger equation is a central difference in a real space difference method for a first type wave function expressed using a propagator. A real-time evolution calculation unit (106) that computes a second-order wave function obtained by applying approximation and expressed by using the Bessel function while developing it by a predetermined time from the initial time; and real-time evolution A calculation result storage unit (108) for storing a calculation result of the second type wave function at each time obtained by developing the calculation unit (106) for each predetermined time;
