Quantum Cosmology in Krylov Space: Complexity and Entropy
Meysam Motaharfar, Maxwell R. Siebersma, Parampreet Singh
We study the quantum dynamics in Krylov space of a spatially flat, homogeneous, and isotropic universe sourced with a massless scalar field within Wheeler-DeWitt (WDW) quantum cosm…
The Steep Price of No Hair in a Modified Loop Quantum Cosmology
Meysam Motaharfar, Parampreet Singh
A modified version of loop quantum cosmology model, the so-called mLQC-I, motivated by Thiemann's regularization of the Hamiltonian constraint, leads to the resolution of the big b…
Echoes of Love Beyond the Horizon: A Bridge to Recovering Information from Black Holes
Meysam Motaharfar, Parampreet Singh
We provide further evidence that information is preserved during black hole evaporation and may be recoverable, provided quantum gravitational effects resolve the singularity. We d…
Love Numbers of Covariant Loop Quantum Black Holes
Meysam Motaharfar, Parampreet Singh
We investigate the linear static response of three covariant loop quantum black holes, namely, the two models proposed by Zhang, Lewandowski, Ma, and Yang (ZLMY) and the Alonso-Bar…
Lessons from gauge fixing and polymerization of loop quantum black holes with a cosmological constant
Geeth Ongole, Parampreet Singh, Anzhong Wang
Loop quantization of Schwarzschild black holes with a cosmological constant for polymerization parameters which are constant is studied in the effective spacetime description. We s…
Loop Quantum Gravitational Signatures via Love Numbers
Meysam Motaharfar, Parampreet Singh
Loop quantum gravitational effects can resolve the central singularity of black holes while potentially leaving tiny traces of quantization in the exterior spacetime. We show the w…
