Transition of the ground state of a classical Φ4 theory in 2 + 1 dimensions is studied from a metastable state into the stable equilibrium. The transition occurs in the broken Z2 symmetry phase and is triggered by a vanishingly small amplitude homogeneous external field h. A phenomenological theory is proposed in form of an effective equation of the order… CONTINUE READING
