Noncommutative 3 Dimensional Soliton from Multi-instantons [PDF]
Journal of High Energy Physics, 2004 We extend the relation between instanton and monopole solutions of the selfduality equations in SU(2) gauge theory to noncommutative space-times. Using this approach and starting from a noncommutative multi-instanton solution we construct a U(2) monopole configuration which lives in 3 dimensional ordinary space. This configuration resembles the Wu-Yang

Area Law Saturation of Entropy Bound from Perturbative Unitarity in Renormalizable Theories
Fortschritte der Physik, Volume 69, Issue 1, January 2021., 2021 Abstract We study the quantum information storage capacity of solitons and baryons in renormalizable quantum field theories that do not include gravity. We observe that a 't Hooft‐Polyakov magnetic monopole saturates the Bekenstein bound on information when the theory saturates the bound on perturbative unitarity.

Unitarity Entropy Bound: Solitons and Instantons
Fortschritte der Physik, Volume 69, Issue 1, January 2021., 2021 Abstract We show that non‐perturbative entities such as solitons and instantons saturate bounds on entropy when the theory saturates unitarity. Simultaneously, the entropy becomes equal to the area of the soliton/instanton. This is strikingly similar to black hole entropy despite absence of gravity. We explain why this similarity is not an accident. We

Relations among topological solitons [PDF]
Phys. Rev. D 105, 105006 (2022), 2022 We clarify relations among topological solitons in various dimensions: a domain wall, non-Abelian vortex, magnetic monopole and Yang-Mills instanton, together with a (non-Abelian) sine-Gordon soliton, baby Skyrmion (lump) and Skyrmion. We construct a composite configuration consisting of a domain wall, vortex, magnetic monopole and Yang-Mills ...

Stable Z-strings with topological polarization in two Higgs doublet model
Journal of High Energy Physics, 2022 We find that a Z-string is stable in a wide range of parameter space of the two Higgs doublet model due to a split into a pair of two topological Z-strings with fractional Z fluxes.

Solitons and exotic instantons [PDF]
Phys. Rev. D104 (2021) 106003, 2021 In this paper, we study the 't Hooft type instantons in eight dimensions, which satisfy the (anti)self-dual equations $F\wedge F=\pm\ast_8F\wedge F$. Using various designs of such instantons, we find new soliton solutions to the low-energy effective theory of the heterotic fivebrane.

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 ...

Monopoles, shockwaves and the classical double copy
Journal of High Energy Physics, 2020 The classical double copy relates exact solutions in biadjoint scalar, gauge and gravity theories. Recently, nonperturbative solutions have been found in biadjoint theory, which have been speculated to be related to the Wu-Yang monopole in gauge theory ...

Instanton worldlines in five-dimensional Ω-deformed gauge theory
Journal of High Energy Physics, 2021 We discuss the Bosonic sector of a class of supersymmetric non-Lorentzian five-dimensional gauge field theories with an SU(1, 3) conformal symmetry. These actions have a Lagrange multiplier which imposes a novel Ω-deformed anti-self-dual gauge field ...

Boundary metrics on soliton moduli spaces
Journal of High Energy Physics, 2022 The geodesic approximation is a powerful method for studying the dynamics of BPS solitons. However, there are systems, such as BPS monopoles in three-dimensional hyperbolic space, where this approach is not applicable because the moduli space metric ...
