Canonical symplectic structure and structurepreserving geometric algorithms for Schrödinger–Maxwell systems
Abstract
An infinite dimensional canonical symplectic structure and structurepreserving geometric algorithms are developed for the photon–matter interactions described by the Schrödinger–Maxwell equations. The algorithms preserve the symplectic structure of the system and the unitary nature of the wavefunctions, and bound the energy error of the simulation for all timesteps. Here, this new numerical capability enables us to carry out firstprinciple based simulation study of important photon–matter interactions, such as the high harmonic generation and stabilization of ionization, with longterm accuracy and fidelity.
