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 ...

Topological strings, strips and quivers
Journal of High Energy Physics, 2019 We find a direct relation between quiver representation theory and open topological string theory on a class of toric Calabi-Yau manifolds without compact four-cycles, also referred to as strip geometries.

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.

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

The volume conjecture and topological strings [PDF]
Fortschritte der Physik, 2009 AbstractIn this paper, we discuss a relation between Jones‐Witten theory of knot invariants and topological open string theory on the basis of the volume conjecture. We find a similar Hamiltonian structure for both theories, and interpret the AJ conjecture as the 𝒟‐module structure for a D‐brane partition function.

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

Orientifolds and the refined topological string [PDF]
Journal of High Energy Physics, 2012 We study refined topological string theory in the presence of orientifolds by counting second-quantized BPS states in M-theory. This leads us to propose a new integrality condition for both refined and unrefined topological strings when orientifolds are present.
