Cyclic universe and uniform rate inflation in loop quantum cosmology
Bikash Chandra Paul, Sahil Saini
We investigate uniform rate inflationary universe in the framework of loop quantum cosmology (LQC) and find that this seemingly simple inflationary model is interlinked with variou…

Ekpyrosis in Quantum Gravitational Anisotropic Bouncing Models
Rachel Brown, A. Meenakshi McNamara, Sahil Saini +1
We explore the isotropization of a model anisotropic universe in the bouncing models using the ekpyrotic potential without assuming initial conditions corresponding to an ekpyrotic…

Spherically symmetric loop quantum gravity: Schwarzschild spacetimes with a cosmological constant
Esteban Mato, Javier Olmedo, Sahil Saini
We provide a quantization of the Schwarzschild spacetime in the presence of a cosmological constant, based on midisuperspace methods developed in the spherically symmetric sector o…
