Does loop quantum scheme permit a black hole formation?
Bao-Fei Li, Parampreet Singh
We explore the way different loop quantization prescriptions affect the formation of trapped surfaces in the gravitational collapse of a homogeneous dust cloud, with a particular e…
Phenomenological implications of modified loop cosmologies: an overview
Bao-Fei Li, Parampreet Singh, Anzhong Wang
In this paper, we first provide a brief review of the effective dynamics of two recently well-studied models of modified loop quantum cosmologies (mLQCs), which arise from differen…
Primordial power spectrum from a matter-Ekpyrotic bounce scenario in loop quantum cosmology
Bao-Fei Li, Sahil Saini, Parampreet Singh
A union of matter bounce and Ekpyrotic scenarios is often studied in an attempt to combine the most promising features of these two models. Since non-perturbative quantum geometric…
Relating dust reference models to conventional systems in manifestly gauge invariant perturbation theory
Kristina Giesel, Bao-Fei Li, Parampreet Singh
Models with dust reference fields in relational formalism have proved useful in understanding the construction of gauge-invariant perturbation theory to arbitrary orders in the can…
Quantum gravitational onset of Starobinsky inflation in a closed universe
Lucia Gordon, Bao-Fei Li, Parampreet Singh
Recent cosmic microwave background observations favor low energy scale inflationary models in a closed universe. However, onset of inflation in such models for a closed universe is…
Primordial scalar power spectrum from the hybrid approach in loop cosmologies
Bao-Fei Li, Javier Olmedo, Parampreet Singh +1
We compare the primordial scalar power spectra in the loop cosmological models using the effective dynamics of the hybrid approach to cosmological perturbations in which the backgr…
