Quantum vacuum inversion and multi-kink unbinding in the non-degenerate double sine-Gordon model
Jonathan Lozano-Mayo
A composite soliton can lose its binding through a change in the ordering of the vacua that fill its interior and its exterior, while the quantum correction to its mass stays small…
Generalized Virial Identities: Radial Constraints for Solitons, Instantons, and Bounces
Jonathan Lozano-Mayo
We derive a continuous family of virial identities for O() symmetric configurations, parameterized by an exponent that controls the radial weighting. The family provides a s…
Multi-kinks and composite oscillons in a commensurable and non degenerate double sine-Gordon model
Jonathan Lozano-Mayo, Manuel Torres-Labansat
In this paper, we introduce a commensurable and non-degenerate double sine-Gordon model, in which a partial breaking of vacuum degeneracy provides a mechanism for the emergence of…
Kink solutions in a generalized scalar field model
Jonathan Lozano-Mayo, Manuel Torres-Labansat
We study a scalar field model in a two dimensional space-time with a generalized potential which has four minima, obtaining novel kink solutions with well defined propertie…
