An invitation to loop quantum gravity [PDF]
, 2004 We describe the basic assumptions and key results of loop quantum gravity, which is a background independent approach to quantum gravity. The emphasis is on the basic physical principles and how one deduces predictions from them, at a level suitable for ...

Spin Entanglement Witness for Quantum Gravity. [PDF]
Physical Review Letters, 2017 Understanding gravity in the framework of quantum mechanics is one of the great challenges in modern physics. However, the lack of empirical evidence has lead to a debate on whether gravity is a quantum entity.

Signatures of the quantum nature of gravity in the differential motion of two masses [PDF]
Quantum Science and Technology, 2021 We show that a signature of the quantum nature of gravity is the quantum mechanical squeezing of the differential motion of two identical masses with respect to their common mode.

Quantum gravity from causal dynamical triangulations: a review [PDF]
Classical and quantum gravity, 2019 This topical review gives a comprehensive overview and assessment of recent results in causal dynamical triangulations, a modern formulation of lattice gravity, whose aim is to obtain a theory of quantum gravity nonperturbatively from a scaling limit of ...

New Journal of Physics, 2005 The goal of this article is to present a broad perspective on quantum gravity for \emph{non-experts}. After a historical introduction, key physical problems of quantum gravity are illustrated. While there are a number of interesting and insightful approaches to address these issues, over the past two decades sustained progress has primarily occurred in

Nuclear Physics B, 2020 We define a three-dimensional quantum theory of gravity as the holographic dual of the Liouville conformal field theory. The theory is consistent and unitary by definition. The corresponding theory of gravity with negative cosmological constant has peculiar properties. The quantum theory has no normalisable AdS3 vacuum. The model contains primary black

Low-dimensional de Sitter quantum gravity [PDF]
Journal of High Energy Physics, 2019 We study aspects of Jackiw-Teitelboim (JT) quantum gravity in two-dimensional nearly de Sitter (dS) spacetime, as well as pure de Sitter quantum gravity in three dimensions.

Scattering amplitudes in affine gravity [PDF]
Phys. Rev. D 103, 105019 (2021), 2020 Affine gravity is a connection-based formulation of gravity that does not involve a metric. After a review of basic properties of affine gravity, we compute the tree-level scattering amplitude of scalar particles interacting gravitationally via the connection in a curved spacetime.
