Topological Nambu monopole in two Higgs doublet models
Physics Letters B, 2020 We show that a topological Nambu monopole exists as a regular solution for a large range of parameters in two Higgs doublet models, contrary to the standard model admitting only non-topological Nambu monopoles.

Advances in Theoretical and Mathematical Physics, 2005 We construct new topological theories related to sigma models whose target space is a seven dimensional manifold of G_2 holonomy. We define a new type of topological twist and identify the BRST operator and the physical states. Unlike the more familiar six dimensional case, our topological model is defined in terms of conformal blocks and not in terms ...

Electroweak axion string and superconductivity
Journal of High Energy Physics, 2021 We study the axion strings with the electroweak gauge flux in the DFSZ axion model and show that these strings, called the electroweak axion strings, can exhibit superconductivity without fermionic zeromodes. We construct three types of electroweak axion

Topological stars, black holes and generalized charged Weyl solutions
Journal of High Energy Physics, 2021 We construct smooth static bubble solutions, denoted as topological stars, in five-dimensional Einstein-Maxwell theories which are asymptotic to ℝ1,3×S1. The bubbles are supported by allowing electromagnetic fluxes to wrap smooth topological cycles.

Topological strings from WZW models [PDF]
, 1994 We show that the BRST structure of the topological string is encoded in the ``small'' N=4 superconformal algebra, enabling us to obtain, in a non-trivial way, the string theory from hamiltonian reduction of A(1|1).

Compactified webs and domain wall partition functions
European Physical Journal C: Particles and Fields, 2017 In this paper we use the topological vertex formalism to calculate a generalization of the “domain wall” partition function of M-strings. This generalization allows calculation of partition function of certain compactified webs using a simple gluing ...

STRINGS AND NON-TOPOLOGICAL SOLITONS [PDF]
Modern Physics Letters A, 1994 We have numerically calculated topological and non-topological solitons in two spatial dimensions with Chern-Simons term. Their quantum stability, as well as that of the Maxwell vortex, is analyzed by means of bounce instantons which involve three-dimensional strings and non-topological solitons.

Non-Abelian strings and domain walls in two Higgs doublet models
Journal of High Energy Physics, 2018 Contrary to the standard model that does not admit topologically nontrivial solitons, two Higgs doublet models admit topologically stable vortex strings and domain walls. We numerically confirm the existence of a topological Z-string confining fractional

Constructing Spin Density Vector Twists With Spin Density Singularity
IEEE Photonics Journal, 2022 In this article, we propose a non-orbital angular momentum (OAM) method for constructing the spiral twists of spin density (SD) vectors in three-dimensional (3D) optical fields. This is realized by generating strings of SD singularities in a longitudinal
