PARAMETRIZING FLUIDS IN CANONICAL QUANTUM GRAVITY [PDF]
International Journal of Modern Physics A, 2008 The problem of time is an unsolved issue of canonical General Relativity. A possible solution is the Brown-Kuchař mechanism which couples matter to the gravitational field and recovers a physical, i.e. non vanishing, observable Hamiltonian functional by manipulating the set of constraints. Two cases are analyzed.

Potential tests of the generalized uncertainty principle in the advanced LIGO experiment
Physics Letters B, 2018 The generalized uncertainty principle and a minimum measurable length arise in various theories of gravity and predict Planck-scale modifications of the canonical position-momentum commutation relation.

Fundamental length scale and the bending of light in a gravitational field
European Physical Journal C: Particles and Fields, 2022 The canonical approach to quantizing quantum gravity is understood to suffer from pathological non-renomalizability. Nevertheless in the context of effective field theory, a viable perturbative approach to calculating elementary processes is possible ...

Hamiltonian Renormalization V: Free Vector Bosons
Frontiers in Astronomy and Space Sciences, 2021 In a recent proposal we applied methods from constructive QFT to derive a Hamiltonian Renormalization Group in order to employ it ultimately for canonical quantum gravity.

Three-dimensional canonical quantum gravity [PDF]
Classical and Quantum Gravity, 1995 General aspects of vielbein representation, ADM formulation and canonical quantization of gravity are reviewed using pure gravity in three dimensions as a toy model. The classical part focusses on the role of observers in general relativity, which will later be identified with quantum observers.

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 $\mathbb H$.

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.

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 ...
