White paper and roadmap for quantum gravity phenomenology in the multi-messenger era
Classical and quantum gravity, 2023The unification of quantum mechanics and general relativity has long been elusive. Only recently have empirical predictions of various possible theories of quantum gravity been put to test, where a clear signal of quantum properties of gravity is still

Introduction to Quantum Field Theory with Applications to Quantum Gravity
, 2021This book focuses on quantum field theory and its application to gravitational physics, in both semiclassical and full quantum frameworks, with special attention paid to renormalization, gauge theories and, especially, effective action formalism.

Foundations of Quantum Cosmology, 2020
Quantum gravity is perhaps the most important open problem in fundamental physics. It is the problem of merging quantum mechanics and general relativity, the two great conceptual revolutions in the physics of the twentieth century.

Symmetries in Quantum Field Theory and Quantum Gravity
Communications in Mathematical Physics, 2018In this paper we use the AdS/CFT correspondence to refine and then establish a set of old conjectures about symmetries in quantum gravity. We first show that any global symmetry, discrete or continuous, in a bulk quantum gravity theory with a CFT dual ...

Quantum Gravity and the Functional Renormalization Group
, 2019During the past two decades the gravitational asymptotic safety scenario has undergone a major transition from an exotic possibility to a serious contender for a realistic theory of quantum gravity.

Action Integrals and Partition Functions in Quantum Gravity
, 1977One can evaluate the action for a gravitational field on a section of the complexified spacetime which avoids the singularities. In this manner we obtain finite, purely imaginary values for the actions of the Kerr-Newman solutions and de Sitter space ...

Quantum gravity is a critical area of research aiming to reconcile the principles of general relativity and quantum mechanics. While general relativity explains the gravitational forces acting on massive bodies, it lacks compatibility with quantum mechanics, which governs the behavior of subatomic particles.
