Axion strings are superconducting

open access: yesJournal of High Energy Physics, 2021
We explore the cosmological consequences of the superconductivity of QCD axion strings. Axion strings can support a sizeable chiral electric current and charge density, which alters their early universe dynamics. We examine the possibility that shrinking

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

open access: yesJournal 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]

open access: yesFortsch.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.

Trieste lectures on solitons in noncommutative gauge theories [PDF]

open access: yes, 2000
We present a pedagogical introduction into noncommutative gauge theories, their stringy origin, and non-perturbative effects, including monopole and instanton ...

Deconstructing KK Monopoles [PDF]

open access: yesJHEP 0308 (2003) 044, 2003
We describe a procedure for finding Kaluza-Klein monopole solutions in deconstructed four and five dimensional supersymmetric gauge theories. In the deconstruction of a four dimensional theory, the KK monopoles are finite-action solutions of the Euclidean equations of motion of the finite lattice spacing theory. The "lattice" KK monopoles can be viewed

Soliton solutions of the fermion-Skyrmion system in (2+1) dimensions

open access: yesJournal of High Energy Physics, 2018
We study effects of backreaction of the fermionic modes localized by the baby Skyrmion in the (2+1)-dimensional Skyrme model. It is shown that there is a tower of fermionic modes of two different types, localized by the soliton, however there is only one

Confinement and moduli locking of Alice strings and monopoles

open access: yesJournal of High Energy Physics, 2021
We argue that strings (vortices) and monopoles are confined, when fields receiving nontrivial Aharonov-Bohm (AB) phases around a string develop vacuum expectation values (VEVs).

Monopole Clustering and Color Confinement in the Multi-Instanton System [PDF]

open access: yesPhys.Rev. D60 (1999) 094504, 1999
We study color confinement properties of the multi-instanton system, which seems to carry an essence of the nonperturbative QCD vacuum. Here we assume that the multi-instanton system is characterized by the infrared suppression of instantons as $f(\rho)\sim \rho^{-5}$ for large size $\rho$.

Recrudescence of massive fermion production by oscillons

open access: yesJournal of High Energy Physics, 2017
We bring together the physics of preheating, following a period of inflation, and the dynamics of non-topological solitons, namely oscillons. We show that the oscillating condensate that makes up an oscillon can be an efficient engine for producing heavy

Abelian Chern-Simons vortices at finite chemical potential

open access: yesJournal of High Energy Physics, 2020
We examine vortices in Abelian Chern-Simons theory coupled to a relativistic scalar field with a chemical potential for particle number or U(1) charge.
