Description
We have discussed the tunnelling effect in FL model. The
tunnelling coefficient is derived in the field configuration space
by calculating the transition amplitude using the path integral at
SPA and the dilute instanton gas approximation. By studying the
tunnelling effect between the two degenerating vacuums at the
critical temperature and chemical potential, we find that the
system could be deconfined by tunnelling, which will change the
first order deconfinement phase transition to crossover. The
$T-\mu$ phase diagram of deconfinement with both first order phase
transition and crossover including CEP is presented.
