Abstract
Spontaneous symmetry breaking usually occurs due to the tachyonic (spinodal) instability of a scalar field near the top of its effective potential at \ensuremath{\varphi}=0.Naively, one might expect the field \ensuremath{\varphi}to fall from the top of the effective potential and then experience a long stage of oscillations with amplitude O(v)near the minimum of the effective potential at \ensuremath{\varphi}=vuntil it gives its...
