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 gravitational dynamics in the presence of generalized, non-extensive horizon entropies. Working within a local Rindler-wedge frame…
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, where the number of accessible configurations grows ex…
Generalized Birkhoff theorems and 2+2 direct pruduct spacetimes in Weyl conformal gravity
Petr Jizba, Tereza LeheÄková
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…
