Analysis of the continuous-configuration time-dependent self-consistent field method applied to system-bath dynamics

摘要

We have implemented and studied the continuous-configuration time-dependent self-consistent field scheme, a variation of the multiconfiguration time-dependent Hartree method, which aims to get around the latter’s exponential scaling problem, especially with regard to system-bath dynamics. We present applications to quantum dissipative dynamics and an analysis of the computational effort. Namely, propagation times within this scheme scale linearly with the number of bath modes. © 2010 American Institute of Physics Article Outline INTRODUCTION THEORY The modified ansatz The new equations of motion THE SYSTEM VIBRATIONAL RELAXATION NUMERICAL PERFORMANCE INELASTIC SCATTERING CONCLUSIONS
