Expectation values of Coherent States for Lattice Gauge Theories
Klaus Liegener, Ernst-Albrecht Zwicknagel
This article investigates properties of semiclassical Gauge Field Theory Coherent States for general quantum gauge theories. Useful, e.g., for the canonical formulation of Lattice…
Challenges in recovering a consistent cosmology from the effective dynamics of loop quantum gravity
Andrea Dapor, Klaus Liegener, Tomasz Pawłowski
We reexamine a set of existing procedures aimed at recovering the effective description of the dynamics of LQG in the context of cosmological solutions. In particular, the studies…
Some physical implications of regularization ambiguities in SU(2) gauge-invariant loop quantum cosmology
Klaus Liegener, Parampreet Singh
The way physics of loop quantum gravity is affected by the underlying quantization ambiguities is an open question. We address this issue in the context of loop quantum cosmology u…
New Loop Quantum Cosmology Modifications from Gauge-covariant Fluxes
Klaus Liegener, Parampreet Singh
Loop quantum cosmology is a symmetry reduced quantization of cosmological spacetimes based on loop quantum gravity. While it has been successful in resolution of various cosmologic…
Perspectives on the dynamics in a loop quantum gravity effective description of black hole interiors
Mehdi Assanioussi, Andrea Dapor, Klaus Liegener
In the loop quantum gravity context, there have been numerous proposals to quantize the reduced phase space of a black hole, and develop a classical effective description for its i…
Emergent de Sitter epoch of the Loop Quantum Cosmos: a detailed analysis
Mehdi Assanioussi, Andrea Dapor, Klaus Liegener +1
We present a detailed analysis of a quantum model for Loop Quantum Cosmology based on strict application of the Thiemann regularization algorithm for the Hamiltonian in Loop Quantu…
