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^

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.

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.

Realization of a two-dimensional Weyl semimetal and topological Fermi strings

Nature Communications
A 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.

Random Generation Topology Coding Technique in Asymmetric Topology Encryption

Mathematics
The security of traditional public key cryptography algorithms depends on the difficulty of the underlying mathematical problems. Asymmetric topological encryption is a graph-dependent encryption algorithm produced to resist attacks by quantum computers ...

Bethe/Gauge correspondence in odd dimension: modular double, non-perturbative corrections and open topological strings [PDF]

, 2016
A bstractBethe/Gauge correspondence as it is usually stated is ill-defined in five dimensions and needs a “non-perturbative” completion; a related problem also appears in three dimensions.

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 ...

Defects in the 3-dimensional toric code model form a braided fusion 2-category

Journal of High Energy Physics, 2020
It was well known that there are e-particles and m-strings in the 3-dimensional (spatial dimension) toric code model, which realizes the 3-dimensional ℤ2 topological order.

ABJM on ellipsoid and topological strings [PDF]

, 2016
A bstractIt is known that the large N expansion of the partition function in ABJM theory on a three-sphere is completely determined by the topological string on local Hirzebruch surface F0$$ {\mathbb{F}}_0 $$.
