QUANTUM GRAVITY BY THE COMPLEX CANONICAL FORMULATION [PDF]
International Journal of Modern Physics D, 1992 The basic features of the complex canonical formulation of general relativity and the recent developments in the quantum gravity program based on it are reviewed. The exposition is intended to be complementary to the review articles already available and some original arguments are included.

Applications of Canonical Quantum Gravity to Cosmology [PDF]
Symmetry, 2019 We applied quantum gravitational results to spatially unbounded Friedmann universes and tried to answer some questions related to dark energy, dark matter, inflation, and the missing antimatter.

Anomaly-free cosmological perturbations in effective canonical quantum gravity [PDF]
, 2014 This article lays out a complete framework for an effective theory of cosmological perturbations with corrections from canonical quantum gravity. Since several examples exist for quantum-gravity effects that change the structure of space-time, the ...

Dust as a standard of space and time in canonical quantum gravity. [PDF]
Physical Review D, Particles and fields, 1994 The coupling of the metric to an incoherent dust introduces into spacetime a privileged dynamical reference frame and time foliation. The comoving coordinates of the dust particles and the proper time along the dust worldlines become canonical ...

Black-hole horizons in modified spacetime structures arising from canonical quantum gravity [PDF]
, 2011 Several properties of canonical quantum gravity modify spacetime structures, sometimes to the degree that no effective line elements exist to describe the geometry.

Journal of High Energy PhysicsWe study the quantum gravity corrected decoherence of quantum superpositions in the near-extremal Reissner-Nordström black holes. By employing the effective field theory approach, we model the black hole as a quantum system coupled to an external source ...

Nonperturbative solutions for canonical quantum gravity: An overview [PDF]
Physics Reports, 1997 In this paper we will make a survey of solutions to the Wheeler-Dewitt equation which have been found up to now in Ashtekar's formulation for canonical quantum gravity. Roughly speaking they are classified into two categories, namely, Wilson-loop solutions and topological solutions.

REVISED CANONICAL QUANTUM GRAVITY VIA THE FRAME FIXING [PDF]
International Journal of Modern Physics D, 2004 We present a new reformulation of the canonical quantum geometrodynamics, which allows one to overcome the fundamental problem of the frozen formalism and, therefore, to construct an appropriate Hilbert space associate to the solution of the restated dynamics.

Time Evolution in Canonical Quantum Gravity is Trivial [PDF]
Annals of PhysicsThe Wheeler-DeWitt (WdW) equation does not describe any explicit time evolution of the wave function, and somehow related to this issue, there is no natural way of defining an invariant inner product that provides a viable probability interpretation.
