Effective Actions for Domain Wall Dynamics
Jose J. Blanco-Pillado, Alberto GarcÃa MartÃn-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…

Feshbach resonances and dynamics of BPS solitons
Alberto GarcÃa MartÃn-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…
