Quantum bounce and cosmic recall
Alejandro Corichi, Parampreet Singh
Loop quantum cosmology predicts that, in simple models, the big bang singularity of classical general relativity is replaced by a quantum bounce. Because of the extreme physical co…
Graceful exit via polymerization of pre-big bang cosmology
Giuseppe De Risi, Roy Maartens, Parampreet Singh
We consider a phenomenological modification of the Pre Big Bang scenario using ideas from the resolution of curvature singularities in Loop Quantum Cosmology. We show that non-pert…
Thermal fluctuations in loop cosmology
Joao Magueijo, Parampreet Singh
Quantum gravitational effects in loop quantum cosmology lead to a resolution of the initial singularity and have the potential to solve the horizon problem and generate a quasi sca…
Loop quantum cosmology of k=1 FRW models
Abhay Ashtekar, Tomasz Pawlowski, Parampreet Singh +1
The closed, k=1, FRW model coupled to a massless scalar field is investigated in the framework of loop quantum cosmology using analytical and numerical methods. As in the k=0 case,…
