摘要：

A variational ground-state wave vector for a tunneling system coupled to a phonon bath is proposed taking into account the possibility of a symmetry breaking in the initial state of a two-state system. A best upper bound to the ground-state energy is found showing the impossibility of localization due to interaction with a phonon bath.
