Quantum Cauchy surfaces in canonical quantum gravity [PDF]
Classical and Quantum Gravity, 2016 For a Dirac theory of quantum gravity obtained from the refined algebraic quantization procedure, we propose a quantum notion of Cauchy surfaces. In such a theory, there is a kernel projector for the quantized scalar and momentum constraints, which maps the kinematic Hilbert space $\mathbb K$ into the physical Hilbert space $\mathbb H$.

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.

Which Quantum Theory Must be Reconciled with Gravity? (And What Does it Mean for Black Holes?)
Universe, 2016 We consider the nature of quantum properties in non-relativistic quantum mechanics (QM) and relativistic quantum field theories, and examine the connection between formal quantization schemes and intuitive notions of wave-particle duality.

Modifications to gravitational wave equation from canonical quantum gravity
European Physical Journal C: Particles and Fields, 2020 It is expected that the quantum nature of spacetime leaves its imprint in all semiclassical gravitational systems, at least in certain regimes, including gravitational waves.

Cauchy slice holography: a new AdS/CFT dictionary
Journal of High Energy Physics, 2023 We investigate a new approach to holography in asymptotically AdS spacetimes, in which time rather than space is the emergent dimension. By making a sufficiently large T 2-deformation of a Euclidean CFT, we define a holographic theory that lives on ...

Inequivalent Canonical Quantizations in Quantum Gravity [PDF]
Progress of Theoretical Physics, 1984 Summary: It is explicitly shown in quantum gravity that given a Lagrangian density up to a total divergence, the equal-time commutators between field operators can depend on the choice of canonical variables. It is shown, however, that canonical quantizations which do not reproduce the equal-time commutators of the manifestly covariant canonical ...

On the area operators of the Husain-Kuchar-Rovelli model and Canonical/Loop Quantum Gravity [PDF]
, 1998 I investigate the relation between an operative definition of the area of a surface specified by matter fields and the area operators recently introduced in the canonical/loop approach to Quantum Gravity and in Rovelli's variant of the Husain-Kuchar ...

Constraining the loop quantum gravity parameter space from phenomenology
Physics Letters B, 2018 Development of quantum gravity theories rarely takes inputs from experimental physics. In this letter, we take a small step towards correcting this by establishing a paradigm for incorporating putative quantum corrections, arising from canonical quantum ...

Toward a Background Independent Quantum Theory of Gravity
, 2004 Any canonical quantum theory can be understood to arise from the compatibility of the statistical geometry of distinguishable observations with the canonical Poisson structure of Hamiltonian dynamics. This geometric perspective offers a novel, background
