Thermodynamic topology of topological charged dilatonic black holes

The European Physical Journal C
AbstractThe aim of this paper is to explore the thermodynamic topology of topological charged dilatonic black holes. To achieve this, our study will begin by examining the characteristics of topological charged black holes in dilaton gravity. Specifically, we will concentrate on the impact of the topological constant on the event horizon of these black

Topological insights into black hole thermodynamics: non-extensive entropy in CFT framework

European Physical Journal C: Particles and Fields
In this paper, we conducted an in-depth investigation into the thermodynamic topology of Einstein-Gauss-Bonnet black holes within the framework of Conformal Field Theory (CFT), considering the implications of non-extensive entropy formulations. Our study

Defects in vibrated monolayers of equilateral triangular prisms

Physical Review Research
We present experimental results in which a quasimonolayer of grains, shaped as equilateral triangular prisms, is vertically vibrated within circular and square confining cavities.

Spin-imbalance induced buried topological edge currents in Mott and topological insulator heterostructures

New Journal of Physics
We theoretically investigate the heterostructure between a ferrimagnetic Mott insulator (MI) and a time-reversal invariant topological band insulator (TI) on the two-dimensional Lieb lattice with periodic boundary conditions.

Topological Charges, Prequarks and Presymmetry: a Topological Approach to Quark Fractional Charges

, 2004
A topological approach to quark fractional charges, based on charge constraints unexplained by the Standard Model of particle physics, is discussed. Charge fractionalization is related to a tunneling process occurring in time between pure gauge field configurations at the far past and future associated with integer-charged bare quarks, named prequarks.

Topological charges and quasi-charges in Absolute Parallelism

, 2006
Absolute Parallelism (AP) has many interesting features: large symmetry group of equations; field irreducibility with respect to this group; vast list of consistent second order equations not restricted to Lagrangian ones. There is the variant of AP which solutions are free of arising singularities if D=5; in this case AP acquires topological features ...
