Feshbach resonances and dynamics of BPS solitons
Alberto García Martín-Caro, Jose Queiruga, Andrzej Wereszczynski
We demonstrate that the geodesic dynamics of BPS solitons can be modified by the excitation of Feshbach resonances, or quasi-bound modes, in a toy model of two scalar fields. A mod…
Effective Actions for Domain Wall Dynamics
Jose J. Blanco-Pillado, Alberto García Martín-Caro, Daniel Jiménez-Aguilar +1
We introduce a systematic method to derive the effective action for domain walls directly from the scalar field theory that gives rise to their solitonic solutions. The effective a…
Sphaleron without shape mode and its oscillon
K. Oles, J. Queiruga, T. Romanczukiewicz +1
We find that an oscillon can possess a characteristic double oscillation structure even though it results in a decay of a sphaleron which does not have any positive energy vibratio…
Semi-BPS sphaleron and its dynamics
A. Alonso-Izquierdo, S. Navarro-Obregón, K. Oles +3
We construct a simple field theory in which a sphaleron, i.e., a saddle-point particle-like solution, forms a semi-BPS state with a background defect that is an impurity. This mean…
Inclusion of radiation in the CCM approach of the model
S. Navarro-Obregón, L. M. Nieto, J. M. Queiruga
We present an effective Lagrangian for the model that includes radiation modes as collective coordinates. The coupling between these modes to the discrete part of the spectru…
Parametric Resonances in Axionic Cosmic Strings
Jose J. Blanco-Pillado, Daniel Jiménez-Aguilar, Jose M. Queiruga +1
In this letter we uncover a new parametric resonance of axionic cosmic strings. This process is triggered by the presence on the string of internal mode excitations that resonantly…
