Canonical “Loop” Quantum Gravity and Spin Foam Models [PDF]
, 2000 The canonical ``loop'' formulation of quantum gravity is a mathematically well defined, background independent, non perturbative standard quantization of Einstein's theory of General Relativity. Some among the most meaningful results of the theory are: 1) the complete calculation of the spectrum of geometric quantities like the area and the volume and ...

From Timeless Physical Theories to Timelessness
Humana.Mente: Journal of Philosophical Studies, 2018 This paper addresses the extent to which both Julian Barbour‘s Machian formulation of general relativity and his interpretation of canonical quantum gravity can be called timeless. We differentiate two types of timelessness in Barbour‘s (1994a, 1994b and

Emergent Time and Time Travel in Quantum Physics
UniverseEntertaining the possibility of time travel will invariably challenge dearly-held concepts in fundamental physics. It becomes relatively easy to construct multiple logical contradictions using differing starting points from various well-established ...

Statistical Thermodynamics of Polymer Quantum Systems
Symmetry, Integrability and Geometry: Methods and Applications, 2011 Polymer quantum systems are mechanical models quantized similarly as loop quantum gravity. It is actually in quantizing gravity that the polymer term holds proper as the quantum geometry excitations yield a reminiscent of a polymer material.

Classical and quantum cosmology of f(R) gravity’s rainbow in Schutz’s formalism
European Physical Journal C: Particles and FieldsWe investigate the classical and quantum dynamics of f(R) gravity’s rainbow in the presence of a perfect fluid, employing Schutz’s formalism to establish a well-defined notion of time. In the classical regime, we derive and solve the equations of motion,
