String topology for Lie groups [PDF]

Journal of Topology, 2010
In 1999 Chas and Sullivan showed that the homology of the free loop space of an oriented manifold admits the structure of a Batalin-Vilkovisky algebra. In this paper we give a direct description of this Batalin-Vilkovisky algebra in the case that the manifold is a compact Lie group G. Our answer is phrased in terms of the homology of G, the homology of

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.

GTI-space : the space of generalized topological indices [PDF]

, 2008
A new extension of the generalized topological indices (GTI) approach is carried out torepresent 'simple' and 'composite' topological indices (TIs) in an unified way.

Stable Z-strings with topological polarization in two Higgs doublet model

Journal of High Energy Physics, 2022
We find that a Z-string is stable in a wide range of parameter space of the two Higgs doublet model due to a split into a pair of two topological Z-strings with fractional Z fluxes.

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.

Observation of vortex-string chiral modes in metamaterials

Nature Communications
As hypothetical topological defects in the geometry of spacetime, vortex strings could have played many roles in cosmology, and their distinct features can provide observable clues about the early universe’s evolution.

Cosmic strings and scalar tensor gravity [PDF]

, 1999
This thesis is concerned with the study of cosmic strings. We studied the values for the Higgs mass and string coupling for which the gravitational effect of an infinite cosmic string in the context of the Einstein theory is not only locally but also ...

Trinion conformal blocks from topological strings

Journal of High Energy Physics, 2020
In this paper we investigate the relation between conformal blocks of Liouville CFT and the topological string partition functions of the rank one trinion theory T 2.
