SU(2) Calorons and Magnetic Monopoles

open access: yes, 1998
We investigate the self-dual Yang-Mills gauge configurations on $R^3\times S^1$ when the gauge symmetry SU(2) is broken to U(1) by the Wilson loop. We construct the explicit field configuration for a single instanton by the Nahm method and show that an ...

Goldstone models in D+1 dimensions, D=3,4,5, supporting stable and zero topological charge solutions [PDF]

open access: yes, 2007
We study finite energy static solutions to a global symmetry breaking Goldstone model described by an isovector scalar field in D+1 spacetime dimensions.

Solitons in the Higgs phase -- the moduli matrix approach --

open access: yes, 2006
We review our recent work on solitons in the Higgs phase. We use U(N_C) gauge theory with N_F Higgs scalar fields in the fundamental representation, which can be extended to possess eight supercharges.

Instanton Bags, High Density Holographic QCD and Chiral Symmetry Restoration [PDF]

open access: yes, 2014
We describe the simplest example of an instanton bag in Euclidean space. It consists of a monopole wall and a Kaluza-Klein monopole wall, lifted to one higher dimension, trapping the instanton charge in the middle.

Quantum Vortex Strings: A Review

open access: yes, 2008
The quantum worldsheet dynamics of vortex strings contains information about the 4d non-Abelian gauge theory in which the string lives. Here I tell this story. The string worldsheet theory is typically some variant of the CP^{N-1} sigma-model, describing

Gauge topology and confinement: an update [PDF]

open access: yes, 2015
In the instanton ensemble the fermionic zero modes collectivize and break chiral symmetry. Recent studies of resulting zero mode zone confirm its very small width and overall importance for lattice simulations. Confinement however has been related with

Adiabatic dynamics of instantons on $S ^4 $ [PDF]

open access: yes, 2016
We define and compute the $L^2$ metric on the framed moduli space of circle invariant 1-instantons on the 4-sphere. This moduli space is four dimensional and our metric is $SO(3) \times U(1)$ symmetric.

Excited oscillons and charge-swapping

open access: yesJournal of High Energy Physics
We show that the charge-swapping phenomenon can be understood as a real valued oscillon carrying an excitation in imaginary direction in the target space.

Instantons in the Higgs Phase

open access: yes, 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.

Moduli spaces of instantons in flag manifold sigma models. Vortices in quiver gauge theories

open access: yesJournal of High Energy Physics
In this paper, we discuss lumps (sigma model instantons) in flag manifold sigma models. In particular, we focus on the moduli space of BPS lumps in general Kähler flag manifold sigma models. Such a Kähler flag manifold, which takes the form U n 1 + ⋯ + n
