Quantum to Classical Transition of Inflationary Perturbations - Continuous Spontaneous Localization as a Possible Mechanism -
Suratna Das, Kinjalk Lochan, Satyabrata Sahu +1
The inflationary paradigm provides a mechanism to generate the primordial perturbations needed to explain the observed large scale structures in the universe. Inflation traces back…
Primordial non-Gaussianity as a signature of pre-inflationary radiation era
Suratna Das
Primordial non-Gaussianity generated in an inflationary model where inflation is preceded by a radiation era is discussed. It is shown that both bispectrum and trispectrum non-Gaus…
Bounds on Spontaneous Collapse model of Quantum Mechanics from formation of CMBR and Standard Cosmology
Suratna Das, Kinjalk Lochan, Angelo Bassi
Continuous Spontaneous Localization (CSL) model of Quantum Mechanics modifies Schrödinger equation by adding non-linear stochastic terms due to which the total energy of a system i…
Lee-Wick radiation induced bouncing universe models
Kaushik Bhattacharya, Yi-Fu Cai, Suratna Das
The present article discusses about the effect of a Lee-Wick partner infested radiation phase of the early universe. As Lee-Wick partners can contribute negative energy density so…
