Multi-Criticality and RG Topology in the Charge-Kondo-Breakdown Scenario in the Cuprates

Stefan Kirchner, Petr Jizba

In this paper, we examine the dynamical charge-Kondo-breakdown scenario proposed for cuprate superconductors within the perspective of renormalization group (RG) topology. By analy…

q-Exponential Random Graphs: higher-order networks from simple constraints

David Dobáš, Diego Garlaschelli, Petr Jizba

Exponential Random Graphs (ERGs) are among the most widely used network models, derived as principled least-bias graph ensembles that maximize Shannon entropy under constraints on…

Thermodynamic Gravity with Non-Extensive Horizon Entropy and Topological Calibration

Marco Figliolia, Petr Jizba, Gaetano Lambiase

We revisit Jacobson's thermodynamic derivation of gravity for generalized, non-extensive horizon entropies and develop a consistent framework in which modified gravitational dynami…

Universality classes, Thermodynamics of Group Entropies, and Black Holes

Henrik Jeldtoft Jensen, Petr Jizba, Piergiulio Tempesta

Conventional Boltzmann--Gibbs statistical mechanics successfully describes systems with weak to moderate correlations, in which the number of accessible configurations grows…

Generalized Birkhoff theorems and 2+2 direct pruduct spacetimes in Weyl conformal gravity

Petr Jizba, Tereza Lehečková

In this paper, we study 2+2 direct product spacetimes sourced by separated electromagnetic and Yang--Mills fields within Weyl conformal gravity. We prove that all such configuratio…

Variation on the theme of Jarzynski's inequality

Dani R. Castellanos, Petr Jizba

The Jarzynski equality, which relates equilibrium free-energy difference to an average of non-equilibrium work, plays a central role in modern non-equilibrium statistical thermodyn…

On the Practical Estimation and Interpretation of Rényi Transfer Entropy

Zlata Tabachová, Petr Jizba, Hynek Lavička +1

Rényi transfer entropy (RTE) is a generalization of classical transfer entropy that replaces Shannon's entropy with Rényi's information measure. This, in turn, introduces a new tun…

Generalized Eddington--Finkelstein Coordinates and Exact Vaidya-Type Solutions in Weyl Conformal Gravity

Petr Jizba, Tereza Lehečková

We study Vaidya-type solutions in Weyl conformal gravity (WCG) using Eddington--Finkelstein-like coordinates. Our considerations focus on spherical as well as hyperbolic and planar…

Newman-Penrose formalism and exact vacuum solutions to conformal Weyl gravity

Petr Jizba, Kamil Mudruňka

We study the exterior solution for a static, spherically symmetric source in Weyl conformal gravity in terms of the Newman--Penrose formalism. We first show that both the static, u…

Typicality, entropy and the generalization of statistical mechanics

Bernat Corominas-Murtra, Rudolf Hanel, Petr Jizba

When at equilibrium, large-scale systems obey conventional thermodynamics because they belong to microscopic configurations (or states) that are typical. Crucially, the typical sta…

Running of the Number of Degrees of Freedom in Quantum Conformal Gravity

Stefano Giaccari, Petr Jizba, Jaroslav Kňap +1

We study how the number of degrees of freedom in Weyl conformal gravity runs with the energy scale from the UV fixed point. To this end we employ two approaches. First, we utilize…

Imprints of Barrow-Tsallis Cosmology in Primordial Gravitational Waves

Petr Jizba, Gaetano Lambiase, Giuseppe Gaetano Luciano +1

Both the Barrow and Tsallis entropies are one-parameter generalizations of the black-hole entropy, with the same microcanonical functional form. The ensuing deformation is quan…
