Perturbative Quantum Gravity and its Relation to Gauge Theory
Living Reviews in Relativity, 2002 In this review we describe a non-trivial relationship between perturbative gauge theory and gravity scattering amplitudes. At the semi-classical or tree-level, the scattering amplitudes of gravity theories in flat space can be expressed as a sum of ...

Quantum fluctuations from thermal fluctuations in Jacobson formalism
European Physical Journal C: Particles and Fields, 2017 In the Jacobson formalism general relativity is obtained from thermodynamics. This is done by using the Bekenstein–Hawking entropy–area relation. However, as a black hole gets smaller, its temperature will increase.

Aspects of Semiclassical Black Holes: Development and Open Problems
Advances in High Energy Physics, 2021 The current work is a review, dedicated to the study of semiclassical aspects of black holes. We begin by briefly looking at the main statements of general relativity.

The origin of the spacetime metric: Bell's `Lorentzian pedagogy' and its significance in general relativity [PDF]
, 1999 The purpose of this paper is to evaluate the `Lorentzian Pedagogy' defended by J.S. Bell in his essay ``How to teach special relativity'', and to explore its consistency with Einstein's thinking from 1905 to 1952.

Advanced Functional Materials, EarlyView.Combinatorial vapor deposition enables independent tuning of Cs/Pb and Br/Cl in wide‐bandgap perovskites. Automated multimodal mapping of 500+ compositions reveals a high‐energy optical transition that correlates with enhanced photoluminescence, defining a practical Cs/Pb window.

Discrete Approaches to Quantum Gravity in Four Dimensions
Living Reviews in Relativity, 1998 The construction of a consistent theory of quantum gravity is a problem in theoretical physics that has so far defied all attempts at resolution. One ansatz to try to obtain a non-trivial quantum theory proceeds via a discretization of space-time and the

Spacetime Emergence: An (In)effective Story
Philosophy of PhysicsPhysicists and philosophers are increasingly prone to regarding our current physical theories as providing ‘effective descriptions’ of real-world systems.

Quantum Gravity: A Primer for Philosophers. [PDF]
, 2008 ‘Quantum Gravity’ does not denote any existing theory: the field of quantum gravity is very much a ‘work in progress’. As you will see in this chapter, there are multiple lines of attack each with the same core goal: to find a theory that unifies, in ...

Reconciling Spacetime and the Quantum: Relational Blockworld and the Quantum Liar Paradox [PDF]
, 2007 The Relational Blockworld (RBW) interpretation of non-relativistic quantum mechanics (NRQM) is introduced. Accordingly, the spacetime of NRQM is a relational, nonseparable blockworld whereby spatial distance is only defined between interacting ...

Advanced Functional Materials, EarlyView.A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient
