Correlations and screening of topological charges in Gaussian random fields [PDF]

, 2003
Two-point topological charge correlation functions of several types of geometric singularity in Gaussian random fields are calculated explicitly, using a general scheme: zeros of n-dimensional random vectors, signed by the sign of their Jacobian ...

Colorful vortex intersections in SU(2) lattice gauge theory and their influences on chiral properties

Journal of High Energy Physics, 2017
We introduce topological non-trivial colorful regions around intersection points of two perpendicular vortex pairs and investigate their influence on topological charge density and eigenmodes of the Dirac operator.

Topological Quantum Field Theory and the Geometric Langlands Correspondence [PDF]

, 2013
In the pioneering work of A. Kapustin and E. Witten, the geometric Langlands program of number theory was shown to be intimately related to duality of GL-twisted N=4 super Yang-Mills theory compactified on a Riemann surface. In this thesis, we generalize

Non-linear composition and infinite conformal symmetry of topologically non-trivial solutions in $$(3+1)$$ ( 3 + 1 ) -dimensional Yang–Mills theory

European Physical Journal C: Particles and Fields, 2021
An infinite-dimensional family of analytic solutions in pure SU(2) Yang–Mills theory at finite density in $$(3+1)$$ ( 3 + 1 ) dimensions is constructed. It is labelled by two integeres (p and q) as well as by a two-dimensional free massless scalar field.

Topological charge, spin, and heat transistor [PDF]

Physical Review B, 2021
Spin pumping consists in the injection of spin currents into a non-magnetic material due to the precession of an adjacent ferromagnet. In addition to the pumping of spin the precession always leads to pumping of heat, but in the presence of spin-orbital entanglement it also leads to a charge current.

Topology and index theorem with a generalized Villain lattice action – a test in 2d

Physics Letters B, 2019
Using 2-d U(1) lattice gauge theory we study two definitions of the topological charge constructed from a generalized Villain action and analyze the implementation of the index theorem based on the overlap Dirac operator.

Probing Topological Charge of Discrete Vortices

Physical Review Applied, 2023
Discrete vortex, formed by a one-dimensional (1D) ring array of lasers, contains high output power as compared to a conventional continuous vortex, therefore, has attracted considerable interest due to widespread applications in various fields. We present a method for probing the magnitude and sign of the topological charge (TC) of an unknown discrete ...
