DOI: 10.1103/4vd6-dml9
Abstract: We investigate black hole solutions within a phenomenological approach to quantum gravity based on spacetime thermodynamics developed by Alonso-Serrano and Li\v{s}ka. The field equations are traceless, similarly to unimodular gravity, and include quadratic curvature corrections.… read more here.
