Bogomol'nyi Equations and Coexistence of Vortices and Antivortices in Generalized Abelian Higgs Theories
Aonan Xu, Yisong Yang
We derive the Bogomol'nyi equations in generalized Abelian Higgs theories which allow the coexistence of vortices and antivortices over a compact Riemann surface or the full plane.…
Nonlinear Problems Inspired by the Born--Infeld Theory of Electrodynamics
Yisong Yang
It is shown that nonlinear electrodynamics of the Born--Infeld theory type may be exploited to shed insight into a few fundamental problems in theoretical physics, including render…
Electromagnetic Asymmetry, Relegation of Curvature Singularities of Charged Black Holes, and Cosmological Equations of State in View of the Born--Infeld Theory
Yisong Yang
It is shown that the Born--Infeld nonlinear electrodynamics with a polynomial type nonlinearity accommodates finite-energy electric point charges but rejects finite-energy magnetic…
Yang--Mills Monopoles in Extremal Reissner--Nordström Black Hole Metric
Xiangqin Zhang, Yisong Yang
We show that the closed-form monotone solution linking two different vacuum states, for the exterior Yang--Mills wave equation over the extremal Reissner--Nordström spacetime found…
Solutions to the Minimization Problem Arising in a Dark Monopole Model in Gauge Field Theory
Xiangqin Zhang, Yisong Yang
We prove the existence of dark monopole solutions in a recently formulated Yang--Mills--Higgs theory model with technical features similar to the classical monopole problems. The s…
Determination of AdS Monopole Wall via Minimization
Lei Cao, Yisong Yang
In this note we solve a minimization problem arising in a recent work of Bolognesi and Tong on the determination of an AdS monopole wall. We show that the problem has a unique solu…
Coexisting Vortices and Antivortices Generated by Dually Gauged Harmonic Maps
Xiaosen Han, Genggeng Huang, Yisong Yang
In this paper we first formulate a dually gauged harmonic map model, suggested from a product Abelian Higgs field theory arising in impurity-inspired field theories, and obtain a n…
Domain Wall Solitons Arising in Classical Gauge Field Theories
Lei Cao, Shouxin Chen, Yisong Yang
Domain wall solitons are basic constructs realizing phase transitions in various field-theoretical models and are solutions to some nonlinear ordinary differential equations descen…
Integer-Squared Laws for Global Vortices in the Born--Infeld Wave Equations
Zhifeng Gao, Sven Bjarke Gudnason, Yisong Yang
A series of quantization identities are established for static vortex solutions governed by the Born--Infeld type actions. These identities are of a universal nature which are indi…
Boundary charges and integral identities for solitons in -dimensional field theories
Sven Bjarke Gudnason, Zhifeng Gao, Yisong Yang
We establish a 3-parameter family of integral identities to be used on a class of theories possessing solitons with spherical symmetry in spatial dimensions. The construction p…
