Meron- and Semi-Vortex-Clusters as Physical Carriers of Topological Charge and Vorticity [PDF]

, 2020
In O(N) non-linear σ-models on the lattice, the Wolff cluster algorithm is based on rewriting the functional integral in terms of mutually independent clusters. Through improved estimators, the clusters are directly related to physical observables.

Spiral phase plate with multiple singularity centers

Компьютерная оптика, 2020
We investigate a multispiral phase plate (MSPP) with multiple centers of phase singularity arbitrarily located in the MSPP plane. Equations to describe the topological charge of an optical vortex in the initial plane immediately behind the MSPP and ...

Thermal Simulations, Open Boundary Conditions and Switches

EPJ Web of Conferences, 2018
SU(N) gauge theories on compact spaces have a non-trivial vacuum structure characterized by a countable set of topological sectors and their topological charge. In lattice simulations, every topological sector needs to be explored a number of times which

Topology of Born-Infeld AdS black holes in 4D novel Einstein-Gauss-Bonnet gravity

Physics Letters B, 2022
The topological classification of critical points of black holes in 4D Einstein-Gauss-Bonnet gravity coupled to Born-Infeld theory is investigated. Considered independently, Born-infeld corrections to the Einstein action alter the topological charge of ...

Comparison of different lattice definitions of the topological charge [PDF]

, 2014
We present a comparison of different definitions of the topological charge on the lattice, using a small-volume ensemble with 2 flavours of dynamical twisted mass fermions.

Spin pumping in ferromagnet-topological insulator-ferromagnetheterostructures

, 2015
Topological insulators (TIs) are enticing prospects for the future of spintronics due to their large spin-orbit coupling and dissipationless, counter-propagating conduction channels in the surface state.

Shape of the hot topological charge density spectral function

, 2022
After motivating an interest in the shape of the topological charge density spectral function in hot Yang-Mills theories, we estimate it with the help of thermally averaged classical real-time simulations, for $N_{\rm c} = 2,3$.

Charges and Electromagnetic Radiation as Topological Excitations [PDF]

Advances in High Energy Physics, 2017
We discuss a model with stable topological solitons in Minkowski space with only three degrees of freedom, the rotational angles of a spatial Dreibein. This model has four types of solitons differing in two topological quantum numbers which we identify with electric charge and spin.
