Infinite conformal symmetry and emergent chiral fields of topologically nontrivial configurations : From Yang-Mills-Higgs theory to the Skyrme model
(2022-11-15)
In this manuscript, we discuss a remarkable phenomenon concerning nonlinear and nonintegrable field theories in (3+1) dimensions, living at finite density and possessing nontrivial topological charges and non-Abelian ...
Some topological aspects in Gauge theories: Singlet chiral anomaly and fractional fermion number
(Universidad de los AndesFísicaFacultad de CienciasDepartamento de Física, 2022-02-21)
This work studies two physical effects derived from considering topological solutions to gauge theories. In particular, for the case of euclidean solutions (instantons), we analyze the singlet chiral anomaly, while for the ...

Model Independent Tests of Skyrmions and Their Holographic Cousins
(AMER PHYSICAL SOC, 2009)
We describe a new exact relation for large N(c) QCD for the long-distance behavior of baryon form factors in the chiral limit. This model-independent relation is used to test the consistency of the structure of several ...
Lorentz Violation and Topologically Trapped Fermions in 2+1 Dimensions
(2018-05-01)
The full spectrum of two-dimensional fermion states in a scalar soliton trap with a Lorentz breaking background is investigated in the context of graphene, where the Lorentz symmetry should not be strictly valid. The field ...
