Proca Q-balls and Q-shells

Journal of High Energy Physics, 2021
Non-topological solitons such as Q-balls and Q-shells have been studied for scalar fields invariant under global and gauged U(1) symmetries. We generalize this frame-work to include a Proca mass for the gauge boson, which can arise either from ...

Non-Abelian Sine-Gordon Solitons: Correspondence between $SU(N)$ Skyrmions and ${\mathbb C}P^{N-1}$ Lumps

, 2015
Topologically stable non-Abelian sine-Gordon solitons have been found recently in the $U(N)$ chiral Lagrangian and a $U(N)$ gauge theory with two $N$ by $N$ complex scalar fields coupled to each other.

Solitons on Branes [PDF]

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

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,

ADHM/Nahm Construction of Localized Solitons in Noncommutative Gauge Theories

, 2001
We study the relationship between ADHM/Nahm construction and ``solution generating technique'' of BPS solitons in noncommutative gauge theories. ADHM/Nahm construction and ``solution generating technique'' are the most strong ways to construct exact BPS ...

Instantons confined by monopole strings

, 2013
It is known that monopoles can be confined by vortex-strings in d=3+1 while vortices can be confined by domain-lines in d=2+1. Here, as a higher dimensional generalization of these, we show that Yang-Mills instantons can be confined by monopole-strings ...

Einstein-Maxwell gravitational instantons and five dimensional solitonic strings [PDF]

, 2006
We study various aspects of four dimensional Einstein-Maxwell multicentred gravitational instantons. These are half-BPS Riemannian backgrounds of minimal N=2 supergravity, asymptotic to R^4, R^3 x S^1 or AdS_2 x S^2.

Kink dynamics in a parametric ϕ 6 system: a model with controllably many internal modes

Journal of High Energy Physics, 2017
We explore a variant of the ϕ 6 model originally proposed in Phys. Rev. D 12 (1975) 1606 as a prototypical, so-called, “bag” model in which domain walls play the role of quarks within hadrons.

Noncommutative Instantons and Solitons [PDF]

Fortsch.Phys. 52 (2004) 596-605, 2004
I explain how to construct noncommutative BPS configurations in four and lower dimensions by solving linear matrix equations. Examples are instantons in D=4 Yang-Mills, monopoles in D=3 Yang-Mills-Higgs, and (moving) solitons in D=2+1 Yang-Mills-Higgs. Some emphasis is on the latter as a showcase for the dressing method.

Trions in 1+1 dimensions [PDF]

, 2010
We consider an Abelian BF-Higgs theory with Nf=2 Higgs fields in 1+1 dimensions. We derive a new BPS-like bound and find topological solitons with tri-charges (topological charge, Q-charge and electric charge).
