Coherent state approach for the (Phi)(sup 6)-lattice model and phase transitions
Abstract
Phase transitions in the lattice version of the Phi(sup 6)-field theory are studied. The generalized coherent states approach is used. In such a way the roles of kinks and bubbles in phase transitions have been reexamined. It is shown via a numerical analysis that first and second order phase transitions appear due to the behavior of kink and bubble excitations.
