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.

Non-extensive entropy and holographic thermodynamics: topological insights

European Physical Journal C: Particles and Fields
In this paper, we delve into the thermodynamic topology of AdS Einstein–Gauss–Bonnet black holes, employing non-extensive entropy formulations such as Barrow, Rényi, and Sharma–Mittal entropy within two distinct frameworks: bulk boundary and restricted ...

Robust recognition of opposite-sign vortex beams topological charges in a turbulent atmosphere by neural networks

Известия Томского политехнического университета: Промышленная кибернетика
In recent years, the problem of transmitting information through atmospheric optical communication channels using vortex laser beams to encode information in topological charge values has been actively investigated.

A rotating one-half topological charge dyon

Journal of Physics G: Nuclear and Particle Physics, 2013
Recently, we have shown the existence of a finite energy one-half monopole. In this paper, we would like to introduce electric charge into the one-half monopole configuration, thus creating a one-half dyon. This one-half dyon possesses finite energy, magnetic dipole moment and angular momentum.

Topology of restricted phase space thermodynamics in Kerr-Sen-Ads black holes

Nuclear Physics B
In this study, we investigate the thermodynamic topology of the Kerr-Sen-Ads black hole in restricted phase space. In the restricted phase space, a new parameter, central charge C, and its conjugate parameter μ are introduced, omitting the well-known PdV

Charge conservation protected topological phases [PDF]

Physical Review B, 2013
We discuss the relation between particle number conservation and topological phases. In four spatial dimensions, we find that systems belonging to different topological phases in the presence of a U(1) charge conservation can be connected adiabatically, i.e., without closing the gap, upon intermediately breaking this local symmetry by a superconducting

Topological classes of thermodynamics of the rotating charged AdS black holes in gauged supergravities

Physics Letters B
In this paper, we investigate the topological numbers of rotating charged AdS black holes in both four- and five-dimensional gauged supergravity theories. Our analysis is conducted within the framework of the thermodynamical topological approach to black
