摘要: Abstract The equation-of-motion phase-matching approach provides an efficient way for calculating a system’s time-dependent polarization in any direction subject to weak laser fields of arbitrary shape. Within this approach, we introduce the Poisson Bracket Mapping Equation and Forward–Backward methods, two approximate solutions quantum–classical Liouville equation, simulating laser-induced response quantum subsystem classical environment. We illustrate by transient absorption signal model photo-induced condensed phase electron transfer reaction. results are found be reasonable agreement with exact results, which is promising applications realistic systems.
