Abstract

Recently, the finite temperature states of the spin-boson model were studied. Here with different techniques in the case of level-splitting zero, the explicit expressions for both the dynamics and the equilibrium states are derived, namely Trotter's product formula and analyticity methods from perturbation theory are used.
