Numerical approach for the evolution of spin-boson systems and its application to the Buck–Sukumar model
We study the evolution properties of spin-boson systems by a systematic numerical iteration approach, which performs well in the whole coupling regime.This approach evaluates a set of coefficients in the formal expansion of the time-dependent Schrödinger equation |t = e -i Ĥt |t = 0 by expanding the initial state …
