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 ...

Realization of a two-dimensional Weyl semimetal and topological Fermi strings
Nature CommunicationsA two-dimensional (2D) Weyl semimetal, akin to a spinful variant of graphene, represents a topological matter characterized by Weyl fermion-like quasiparticles in low dimensions.

Instanton effects in rank deformed superconformal Chern-Simons theories from topological strings [PDF]
, 2017 A bstractIn the so-called (2, 2) theory, which is the U(N)4 circular quiver superconformal Chern-Simons theory with levels (k, 0, −k, 0), it was known that the instanton effects are described by the free energy of topological strings whose Gopakumar-Vafa

Spectral sequences in string topology [PDF]
Algebraic & Geometric Topology, 2011 In this paper, we investigate the behaviour of the Serre spectral sequence with respect to the algebraic structures of string topology in generalized homology theories, specificially with the Chas-Sullivan product and the corresponding coproduct and module structures. We prove compatibility for two kinds of fibre bundles: the fibre bundle $ ^n M \to L^

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

Topological strings on singular elliptic Calabi-Yau 3-folds and minimal 6d SCFTs [PDF]
, 2017 A bstractWe apply the modular approach to computing the topological string partition function on non-compact elliptically fibered Calabi-Yau 3-folds with higher Kodaira singularities in the fiber.

Rational maps and string topology [PDF]
Geometry & Topology, 2006 We apply a version of the Chas-Sullivan-Cohen-Jones product on the higher loop homology of a manifold in order to compute the homology of the spaces of continuous and holomorphic maps of the Riemann sphere into a complex projective space. This product makes sense on the homology of maps from a co-H space to a manifold, and comes from a ring spectrum ...

TOPOLOGICAL STRINGS ON NONCOMMUTATIVE MANIFOLDS [PDF]
International Journal of Geometric Methods in Modern Physics, 2004 We identify a deformation of the N=2 supersymmetric sigma model on a Calabi–Yau manifold X which has the same effect on B-branes as a noncommutative deformation of X. We show that for hyperkähler X such deformations allow one to interpolate continuously between the A-model and the B-model.

String topology of classifying spaces [PDF]
Journal für die reine und angewandte Mathematik (Crelles Journal), 2012 53 pages. Section 3 on Props and fields theories rewritten. Section 4 expanded in new sections 4, 5, 6 and 7, to fix orientation problems, finite groups case detailed in section 7. Appendix on signs added. The rest of the sections almost unchanged. Some slight improvements on some results.
