Classical and quantum cosmology of f(R) gravity’s rainbow in Schutz’s formalism

open access: yesEuropean Physical Journal C: Particles and Fields
We 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,

Statistical Thermodynamics of Polymer Quantum Systems

open access: yesSymmetry, 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.

Quantum Schwarzschild-(A)dS black holes: unitarity and singularity resolution

open access: yesJournal of High Energy Physics
We 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.
