Dynamics of apparent horizons in quantum gravitational collapse
Yaser Tavakoli, Joao Marto, Andrea Dapor
We study the gravitational collapse of a massless scalar field within the effective scenario of loop quantum gravity. Classical singularity is avoided and replaced by a quantum bou…
Quantum field theory on LQC Bianchi spacetimes
Andrea Dapor, Jerzy Lewandowski, Yaser Tavakoli
Quantum theory of a scalar field is developed on the LQC Bianchi I space-time. By comparing the the quantum field theory for a single mode on classical and quantum background geome…
Loop quantum cosmology for nonminimally coupled scalar field
Michal Artymowski, Andrea Dapor, Tomasz Pawlowski
We perform a LQC-quantization of the FRW cosmological model with nonminimally coupled scalar field. Making use of a canonical transformation, we recast the theory in the minimally…
Smooth Big Bounce from Affine Quantization
Herve Bergeron, Andrea Dapor, Jean Pierre Gazeau +1
We examine the possibility of dealing with gravitational singularities on a quantum level through the use of coherent state or wavelet quantization instead of canonical quantizatio…
Relational Evolution of Observables for Hamiltonian-Constrained Systems
Andrea Dapor, Wojciech Kamiński, Jerzy Lewandowski +1
Evolution of systems in which Hamiltonians are generators of gauge transformations is a notion that requires more structure than the canonical theory provides. We identify and stud…
Semiclassical dynamics of horizons in spherically symmetric collapse
Yaser Tavakoli, Joao Marto, Andrea Dapor
In this work, we consider a semiclassical description of the spherically symmetric gravitational collapse with a massless scalar field. In particular, we employ an effective scenar…
