Topological G2 and Spin(7) strings at 1-loop from double complexes
Journal of High Energy Physics, 2022 We study the topological G 2 and Spin(7) strings at 1-loop. We define new double complexes for supersymmetric NSNS backgrounds of string theory using generalised geometry.

S-duality and Topological Strings [PDF]
Journal of High Energy Physics, 2004 In this paper we show how S-duality of type IIB superstrings leads to an S-duality relating A and B model topological strings on the same Calabi-Yau as had been conjectured recently: D-instantons of the B-model correspond to A-model perturbative amplitudes and D-instantons of the A-model capture perturbative B-model amplitudes.

Intertwining operator and integrable hierarchies from topological strings
Journal of High Energy Physics, 2021 In [1], Nakatsu and Takasaki have shown that the melting crystal model behind the topological strings vertex provides a tau-function of the KP hierarchy after an appropriate time deformation.

Topological Strings and Integrable Hierarchies [PDF]
Communications in Mathematical Physics, 2005 We consider the topological B-model on local Calabi-Yau geometries. We show how one can solve for the amplitudes by using W-algebra symmetries which encodes the symmetries of holomorphic diffeomorphisms of the Calabi-Yau. In the highly effective fermionic/brane formulation this leads to a free fermion description of the amplitudes. Furthermore we argue

Instantons, Topological Strings, and Enumerative Geometry [PDF]
Advances in Mathematical Physics, 2010 We review and elaborate on certain aspects of the connections between instanton counting in maximally supersymmetric gauge theories and the computation of enumerative invariants of smooth varieties. We study in detail three instances of gauge theories in

Quantum dynamics of topological strings in a frustrated Ising antiferromagnet
npj Quantum Materials, 2022 We investigate the quantum dynamics of the antiferromagnetic transverse field Ising model on the triangular lattice through large-scale quantum Monte Carlo simulations and stochastic analytic continuation.

Hypermultiplets and topological strings [PDF]
Journal of High Energy Physics, 2006 The c-map relates classical hypermultiplet moduli spaces in compactifications of type II strings on a Calabi-Yau threefold to vector multiplet moduli spaces via a further compactification on a circle. We give an off-shell description of the c-map in N=2 superspace.

Topology in thermodynamics of regular black strings with Kaluza–Klein reduction
European Physical Journal C: Particles and Fields, 2023 We study the topological defects in the thermodynamics of regular black strings (from a four-dimensional perspective) that is symmetric under the double Wick rotation and constructed in the high-dimensional spacetime with an extra dimension compactified ...

Realization of non-Hermitian Hopf bundle matter
Communications Physics, 2023 Non-trivial linking invariant encodes robust information of topological matter. It has been recently shown that the linking and winding of complex eigenenergy strings can classify one-dimensional non-Hermitian topological matter.
