The Moduli Space of BPS Domain Walls [PDF]
, 2002 N=2 SQED with several flavors admits multiple, static BPS domain wall solutions. We determine the explicit two-kink metric and examine the dynamics of colliding domain walls.

False vacuum decay in gauge theory
Journal of High Energy Physics, 2017 The decay rate of a false vacuum is studied in gauge theory, paying particular attention to its gauge invariance. Although the decay rate should not depend on the gauge parameter ξ according to the Nielsen identity, the gauge invariance of the result of ...

Notes on Yang-Mills--Higgs monopoles and dyons on R^D, and Chern-Simons--Higgs solitons on \R^{D-2}: Dimensional reduction of Chern-Pontryagin densities [PDF]
, 2011 We review work on construction of Monopoles in higher dimensions. These are solutions to a particular class of models descending from Yang--Mills systems on even dimensional bulk, with Spheres as codimensions.

Composite topological solitons consisting of domain walls, strings, and monopoles in O(N) models
Journal of High Energy Physics, 2023 We study various composites of global solitons consisting of domain walls, strings, and monopoles in linear O(N) models with N = 2 and 3. Spontaneous symmetry breaking (SSB) of the O(N) symmetry down to O(N – 1) results in the vacuum manifold S N−1 ...

Journal of High Energy Physics, 2018 We derive a one-parameter family of gauged Skyrme models from Yang-Mills theory on S 1 × ℝ3, in which skyrmions are well-approximated by calorons and monopoles.

Decay of I-ball/oscillon in classical field theory
Journal of High Energy Physics, 2019 I-balls/oscillons are long-lived and spatially localized solutions of real scalar fields. They are produced in various contexts of the early universe in, such as, the inflaton evolution and the axion evolution.

Solitons in Supersymmetric Gauge Theories: Moduli Matrix Approach [PDF]
, 2006 We review our recent works on solitons in U(Nc) gauge theories with Nf (>Nc) Higgs fields in the fundamental representation, which possess eight supercharges.

Heun Functions and Some of Their Applications in Physics
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 Most of the theoretical physics known today is described by using a small number of differential equations. For linear systems, different forms of the hypergeometric or the confluent hypergeometric equations often suffice to describe the system studied.

Supersymmetric Quantum Mechanics and Topology
Advances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016 Supersymmetric quantum mechanical models are computed by the path integral approach. In the β → 0 limit, the integrals localize to the zero modes. This allows us to perform the index computations exactly because of supersymmetric localization, and we will show how the geometry of target space enters the physics of sigma models resulting in the ...
