Title:Multi-kinks in scalar field theories with non-degenerate vacua: The commensurable and non degenerate double sine-Gordon model
View PDF HTML (experimental)Abstract:This paper considers generic scalar fields models in one space dimension,the potentials of which have several vacuum states. It is shown that the partial breaking of the vacuum degeneracy provides a mechanism for the appearance of static multi-kinks, whenever some false vacuum states appear between two true vacuum states. A multi-kink is a stable field configuration with an internal structure, consisting of various localized energy packages with well-defined separations between them. General results for multi-kinks properties are presented. We introduce the commensurable and non degenerate double sine-Gordon model as a specific realization of this mechanism, supporting the existence of multi-kinks with an arbitrary $n$-number of subkinks. The multi-kinks properties are thoroughly analyzed including the novel phenomenology displayed when two of them collide.
