These lectures give an introduction to the quantum physics of black holes, including recent
developments based on quantum information theory such as the firewall paradox and its …

Extended Theories of Gravity can be considered as a new paradigm to cure shortcomings of
General Relativity at infrared and ultraviolet scales. They are an approach that, by …

In this paper, we extend our previous work [D. Wu, Phys. Rev. D 107, 024024 (2023)
PRVDAQ 2470-0010 10.1103/PhysRevD. 107.024024] to the more general cases with a …

In holographic duality an eternal Anti-de Sitter black hole is described by two copies of the
boundary Conformal Field Theory in the thermal field double state. In this paper we provide …

A bstract We propose that a class of new topologies, for which there is no classical solution,
should be included in the path integral of three-dimensional pure gravity, and that their …

A bstract After turning on an interaction that couples the two boundaries of an eternal BTZ
black hole, we find a quantum matter stress tensor with negative average null energy, whose …

A bstract Recent work by Zamolodchikov and others has uncovered a solvable irrelevant
deformation of general 2D CFTs, defined by turning on the dimension 4 operator\(T\overline …

A bstract We expand on our results in [1] to present a broad new class of gravitational
observables in asymptotically Anti-de Sitter space living on general codimension-zero …

In holographic duality an eternal anti–de Sitter black hole is described by two copies of the
boundary conformal field theory in the thermal field double state. This identification has …

General Relativity has shown an outstanding observational success in the scales where it
has been directly tested. However, modifications have been intensively explored in the …
