Abstract
Based on the nontopological soliton model, a new picture for the deconfinement phase transition is proposed. The relation between the existence of the soliton solution and the nonlinearity of the potential function is analyzed. The effective potential and the equation satisfied by its extrema are given at finite temperature. It turns out that, in this model, at a critical temperature the physical vacuum is transformed into a perturbative vacuum, the soliton solution disappears, and the deconfinement transition occurs.
