phi^4 Kinks - Gradient Flow and Dynamics
arXiv:hep-th/9605038 · doi:10.1088/0951-7715/10/1/002
Abstract
The symmetric dynamics of two kinks and one antikink in classical (1+1)-dimensional $Ï^4$ theory is investigated. Gradient flow is used to construct a collective coordinate model of the system. The relationship between the discrete vibrational mode of a single kink, and the process of kink-antikink pair production is explored.
