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.
