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 ...

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 ...

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

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

Universal character, phase model and topological strings on $$\pmb {\mathbb {C}^3}$$ [PDF]
The European Physical Journal C, 2017 In this paper, we consider two different subjects: the algebra of universal characters$$S_{[\lambda ,\mu ]}(\mathbf{x},\mathbf{y})$$S[λ,μ](x,y)(a generalization of Schur functions) and the phase model of strongly correlated bosons.

Checks of integrality properties in topological strings [PDF]
, 2017 A bstractTests of the integrality properties of a scalar operator in topological strings on a resolved conifold background or orientifold of conifold backgrounds have been performed for arborescent knots and some non-arborescent knots. The recent results
