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…
