't Hooft-Polyakov monopole and instanton-like topological solution in gauge-Higgs unification [PDF]
J.Phys.Soc.Jpn.89(2020)084101, 2019 We consider 't Hooft-Polyakov monopole (TPM) as a topological soliton in the 5-dimensional (5D) theory of gauge-Higgs unification. This scenario provides a very natural framework to incorporate the TPM, since the adjoint scalar is builtin as the extra-space component of higher dimensional gauge field. In the process of the analysis, we realize that the

On catalyzed vacuum decay around a radiating black hole and the crisis of the electroweak vacuum
Journal of High Energy Physics, 2020 False vacuum decay is a key feature in quantum field theories and exhibits a distinct signature in the early Universe cosmology. It has recently been suggested that the false vacuum decay is catalyzed by a black hole (BH), which might cause the ...

Journal of High Energy PhysicsIn this article we study a modification of axion physics in which the dual axion acquires a mass. This mass explicitly breaks the shift symmetry of the dual axion. The potential breaking of this shift symmetry poses a dual axion quality problem. When the

Josephson instantons and Josephson monopoles in a non-Abelian Josephson junction [PDF]
Phys. Rev. D 92, 045010 (2015), 2015 Non-Abelian Josephson junction is a junction of non-Abelian color superconductors sandwiching an insulator, or non-Abelian domain wall if flexible, whose low-energy dynamics is described by a $U(N)$ principal chiral model with the conventional pion mass.

Dynamically assisted Sauter-Schwinger effect — non-perturbative versus perturbative aspects
Journal of High Energy Physics, 2017 The Sauter-Schwinger effect predicts the creation of electron-positron pairs out of the quantum vacuum by a strong and slowly varying electric field.

Journal of High Energy Physics, 2022 We study static solutions of the standard Skyrme model with a pion mass. Using approximately 105 pseudo-random initial configurations made of single Skyrmions in the non-symmetrized product Ansatz and an automatic detection of repeated solutions, we find

Instantons in the Higgs Phase [PDF]
Phys.Rev. D72 (2005) 025011, 2004 When instantons are put into the Higgs phase, vortices are attached to instantons. We construct such composite solitons as 1/4 BPS states in five-dimensional supersymmetric U(Nc) gauge theory with Nf(>=Nc) fundamental hypermultiplets. We solve the hypermultiplet BPS equation and show that all 1/4 BPS solutions are generated by an Nc x Nf matrix which ...

A falling magnetic monopole as a holographic local quench
Journal of High Energy Physics, 2021 An analytic static monopole solution is found in global AdS4, in the limit of small backreaction. This solution is mapped in Poincaré patch to a falling monopole configuration, which is dual to a local quench triggered by the injection of a condensate ...

Confinement and Topological Charge in the Abelian Gauge of QCD [PDF]
Nucl.Phys.Proc.Suppl. 53 (1997) 528-530, 1996 We study the relation between instantons and monopoles in the abelian gauge. First, we investigate the monopole in the multi-instanton solution in the continuum Yang-Mills theory using the Polyakov gauge. At a large instanton density, the monopole trajectory becomes highly complicated, which can be regarded as a signal of monopole condensation. Second,

The self-dual classical double copy, and the Eguchi-Hanson instanton
Journal of High Energy Physics, 2019 The double copy is a map from non-abelian gauge theories to gravity, that has been demonstrated both for scattering amplitudes and exact classical solutions.
