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 ...

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.

Dynamics of global and local vortices with orientational moduli
Journal of High Energy Physics, 2021 The dynamics of both global and local vortices with non-Abelian orientational moduli is investigated in detail. Head-on collisions of these vortices are numerically simulated for parallel, anti-parallel and orthogonal internal orientations where we find ...

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 ...

Vacuum decays around spinning black holes
Journal of High Energy Physics, 2020 We investigate a vacuum decay around a spinning seed black hole by using the Israel junction condition and conclude that the spin of black hole would suppress a vacuum decay rate compared to that for a non-spinning case, provided that the surface of ...

Fractional Skyrmion molecules in a ℂP N−1 model
Journal of High Energy Physics, 2021 We study fractional Skyrmions in a ℂP 2 baby Skyrme model with a generalization of the easy-plane potential. By numerical methods, we find stable, metastable, and unstable solutions taking the shapes of molecules.

Black holes, oscillating instantons and the Hawking-Moss transition
Journal of High Energy Physics, 2020 Static oscillating bounces in Schwarzschild de Sitter spacetime are investigated. The oscillating bounce with many oscillations gives a super-thick bubble wall, for which the total vacuum energy increases while the mass of the black hole decreases due to

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 ...

Journal of High Energy Physics, 2023 Q-lumps are spinning planar topological solitons with stationary solutions that satisfy first-order Bogomolny equations. Q-lump scattering has previously been studied only in the charge two sector, by approximating time evolution by motion in the moduli ...
