Quantization of Brane-Skyrmions via Physics-Informed Neural Networks
Jose A. R. Cembranos, Alberto García Martín-Caro, Sergio S. Rentero
In this work, we investigate the canonical quantization of topological solitons appearing in braneworld scenarios. In particular, we focus on Brane-Skyrmions, topological field con…
Spinning boson stars in nonlinear sigma models and Universal Relations
Christoph Adam, Jorge Castelo Mourelle, Alberto García Martín-Caro +1
Boson stars are hypothetical compact objects derived from solutions of a self-gravitating complex scalar field. In this study, we extend the traditional models by generalizing the…
Instanton Corrections to the MSTB Kink Mass
Jarah Evslin, Alberto García Martín-Caro, Andrzej Wereszczyński
The Montonen-Sarker-Trullinger-Bishop (MSTB) model enjoys two classically degenerate kink solutions in the same topological sector. We construct the instanton that interpolates bet…
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…
