Time and Quantum Theory: A History and A Prospectus [PDF]
, 2013 In this paper I am concerned with analyzing in detail how ideas and expectations regarding the role of time in quantum theory arose and evolved in the early years of quantum mechanics (from 1925-27).

CANONICAL ALGEBRA OF GL(4)-INVARIANT GRAVITY
, 1990 The authors study the canonical form of a generalised formulation of Einstein's theory of gravity which exhibits invariance under local GL(4) transformations. The algebra of constraints is explicitly derived.

Canonical Loop Quantum Gravity
This article presents a comprehensive and self-contained review of Loop Quantum Gravity (LQG), focusing on both its canonical (Hamiltonian) formulation and covariant (spin foam) path integral approach. Beginning with the reformulation of General Relativity using Ashtekar–Barbero variables, it systematically constructs the kinematical Hilbert space ...

The Representation of Time and Change in Mechanics [PDF]
, 2005 This paper is concerned with the representation of time and change in classical (i.e., non-quantum) physical theories. One of the main goals is to attempt to clarify the nature and scope of the so-called problem of time: a knot of technical and ...

Quantum Schwarzschild-(A)dS black holes: unitarity and singularity resolution
Journal of High Energy PhysicsWe consider the canonical quantisation of spherically symmetric spacetimes within unimodular gravity, leaving sign choices in the metric general enough to include both the interior and exterior Schwarzschild-(Anti-)de Sitter spacetime.

Epistemology of Canonical Quantum Gravity - Loop Quantum Gravity [PDF]
In the interpretation of canonical quantum gravity (CQG), gravity appears as a geometric pseudoforce, is reduced to spacetime geometry and becomes a simple effect of spacetime curvature.

Canonical quantum gravity: fundamentals and recent developments
, 2014 This book aims to present a pedagogical and self-consistent treatment of the canonical approach to Quantum Gravity, starting from its original formulation to the most recent developments in the field.
