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

On the Topological Entropy of Some Skew-Product Maps

Entropy, 2013
The aim of this short note is to compute the topological entropy for a family of skew-product maps, whose base is a subshift of finite type, and the fiber maps are homeomorphisms defined in one dimensional spaces.

Emergent Spin Supersolids in Frustrated Quantum Materials

Advanced Materials, EarlyView.
This review highlights developments in the study of spin super‐solids in frustrated quantum materials. Advanced experimental characterizations and computational studies enable a comprehensive understanding of the driving mechanisms of spin super‐solidity in various layered transition‐metal compounds, bridging materials, experiments, and theory aspects.

Topological classifier for detecting the emergence of epileptic seizures

BMC Research Notes, 2018
Objective An innovative method based on topological data analysis is introduced for classifying EEG recordings of patients affected by epilepsy. We construct a topological space from a collection of EEGs signals using Persistent Homology; then, we ...

Dynamics of real projective transformations

Applied General Topology, 2018
The dynamics of a projective transformation on a real projective space are studied in this paper. The two main aspects of these transformations that are studied here are the topological entropy and the zeta function.

Topological Entropy and Sequence Entropy for Hom Tree-Shifts on Unexpandable Trees [PDF]

This article explores the topological entropy and topological sequence entropy of hom tree-shifts on unexpandable trees. Regarding topological entropy, we establish that the entropy, denoted as \(h({\mathcal {T}}_X)\) on an unexpandable tree, equals the

Topological order and topological entropy in classical systems [PDF]

, 2007
We show that the concept of topological order, introduced to describe ordered quantum systems which cannot be classified by broken symmetries, also applies to classical systems.
