Abstract:

For the quantum particle in a double-well potential, approximated by a two-level spin-boson model, we prove the unicity of the equilibrium state at all temperatures, i.e. the absence of localization. This can be understood on the basis of an exact computation of the transition probability between the thermal wave functions of the two minima. © IOP Publishing Ltd.
