New Z3 strings

Physics Letters B, 2016
We consider a Yang–Mills–Higgs theory with the gauge group SU(3) broken to its center Z3 by two scalar fields in the adjoint representation and obtain new Z3 strings asymptotic configurations with the gauge field and magnetic field in the direction of ...

Nonperturbative refined topological string [PDF]

arXiv
A formula for the full nonperturbative topological string free energy was recently proposed by Hattab and Palti \cite{HP24a}. In this work, we extend their result to the refined topological string theory. We demonstrate that the proposed formula for the full nonperturbative refined topological string free energy correctly reproduces the trans-series ...

Classification of virtual string links up to cobordism [PDF]

arXiv, 2019
Cobordism of virtual string links on $n$ strands is a combinatorial generalization of link cobordism. There exists a bijection between virtual string links up to cobordisms and elements of the group $\mathbb{Z}^{n(n-1)}$. This paper also shows that virtual string links up to unwelded equivalence are classified by those groups.

Electromagnetic vacuum fluctuations around a cosmic string in de Sitter spacetime

European Physical Journal C: Particles and Fields, 2017
The electromagnetic field correlators are evaluated around a cosmic string in background of $$(D+1)$$ ( D + 1 ) -dimensional dS spacetime assuming that the field is prepared in the Bunch–Davies vacuum state.

Checks of integrality properties in topological strings

Journal of High Energy Physics, 2017
Tests 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.

An elementary proof of the string topology structure of compact oriented surfaces [PDF]

arXiv, 2011
We give a new proof of the string topology structure of a compact oriented surface of genus g greater than or equal to 2, using elementary algebraic topology. This reproves the result of Vaintrob.

Superconformal partition functions and non-perturbative topological strings

Journal of High Energy Physics, 2018
We propose a non-perturbative definition for refined topological strings. This can be used to compute the partition function of superconformal theories in 5 dimensions on squashed S 5 and the superconformal index of a large number of 6 dimensional (2, 0)

Strings in metric spaces [PDF]

arXiv
We introduce strings in metric spaces and define string complexes of metric spaces. We describe the class of 2-dimensional topological spaces which arise in this way from finite metric spaces.

M-Theory and Topological Strings--II [PDF]

arXiv, 1998
It is shown how the topological string amplitudes encode the BPS structure of wrapped M2 branes in M-theory compactification on Calabi-Yau threefolds. This in turn is related to a twisted supersymmetric index in 5 dimensions which receives contribution only from BPS states.
