O(N) invariance of the multi-field bounce

Journal of High Energy Physics, 2017
In his 1977 paper on vacuum decay in field theory: The Fate of the False Vacuum, Coleman considered the problem of a single scalar field and assumed that the minimum action tunnelling field configuration, the bounce, is invariant under O(4) rotations in ...

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 ...

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.

On Lax pairs and matrix extended simple Toda systems

International Journal of Mathematics and Mathematical Sciences, Volume 2005, Issue 17, Page 2735-2747, 2005., 2005
A A1 Toda system is extended via Lax pair formulations in order to probe noncommutative variables extensions. Systems, some solvable, are built using matrix generalizations.

Geometrical and topological foundations of theoretical physics: from gauge theories to string program

International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 34, Page 1777-1836, 2004., 2004
We study the role of geometrical and topological concepts in the recent developments of theoretical physics, notably in non‐Abelian gauge theories and superstring theory, and further we show the great significance of these concepts for a deeper understanding of the dynamical laws of physics.

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 ...

Generalization of instanton-induced inflation and dynamical compactification

Journal of High Energy Physics, 2023
It was shown that Yang-Mills instantons on an internal space can trigger the expansion of our four-dimensional universe as well as the dynamical compactification of the internal space.

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 ...

1/2, 1/4 and 1/8 BPS Equations in SUSY Yang-Mills-Higgs Systems -- Field Theoretical Brane Configurations --

, 2005
We systematically classify 1/2, 1/4 and 1/8 BPS equations in SUSY gauge theories in d=6, 5, 4, 3 and 2 with eight supercharges, with gauge groups and matter contents being arbitrary.

Solitons on Branes [PDF]

, 1999
We examine the possibility that gauge field configurations on stacks of parallel Dp branes support topological solitons.
