Study of the Coupling Dependence of Relaxation Rates in a Model of Low-Temperature Tunneling Dynamics
A model of low-temperature tunneling dynamics in a double-well system is studied. The various relaxation rates in the problem are computed as a function of the system-bath coupling strengths. An interpretation of frictional effects is made that permits comparison between the quantum tunneling system and classical and semiclassical barrier hopping models of excitation transfer in double-well systems.
