| Abstract: | We investigate the real-time dynamics of a particle in a double well coupled to phonons with ohmic dissipation. We refine previous results about the T=0 symmetry breaking: the critical behaviour of the order parameter is displayed and the symmetry is shown to be only fully broken for infinite coupling. |
