Thermal RG flow of AS quantum gravity
Published 2025-05-01“…We perform the thermal Renormalization Group (RG) study of the Asymptotically Safe (AS) quantum gravity in the Einstein-Hilbert truncation by relating the temperature parameter to the running RG scale as T≡kT=τk (in natural units) in order to determine its thermal evolution in terms of the dimensionless temperature τ which is associated with the temperature of the expanding Universe. …”

Relative quantum gravity: localized gravity and the swampland
Published 2025-08-01“…They realize what we call relative quantum gravity: to become consistent at the quantum level, these gravity theories must be defined as relative to a host higher-dimensional gravity theory. …”

Holographic Screens in Ultraviolet Self-Complete Quantum Gravity
Published 2014-01-01“…This paper studies the geometry and the thermodynamics of a holographic screen in the framework of the ultraviolet self-complete quantum gravity. To achieve this goal we construct a new static, neutral, nonrotating black hole metric, whose outer (event) horizon coincides with the surface of the screen. …”

Shadows of rotating black holes in effective quantum gravity
Published 2025-08-01“…Abstract Recently, two new spherically symmetric black hole models with covariance have been proposed in effective quantum gravity. Based on these models, we use the modified Newman–Janis algorithm to generate two rotating quantum-corrected black hole solutions, characterized by three parameters, the mass M, the spin a, and the quantum parameter $$\zeta $$ ζ . …”

De Sitter quantum gravity and the emergence of local algebras
Published 2025-04-01“…Abstract Quantum theories of gravity are generally expected to have some degree of non-locality, with familiar local physics emerging only in a particular limit. Perturbative quantum gravity around backgrounds with isometries and compact Cauchy slices provides an interesting laboratory in which this emergence can be explored. …”
