Revisiting a pre-inflationary radiation era and its effect on the CMB power spectrum
Suratna Das, Gaurav Goswami, Jayanti Prasad +1
We revisit the scenario where inflation is preceded by a radiation era by considering that the inflaton too could have been in thermal equilibrium early in the radiation era. Hence…
Higgs vacuum stability and inflationary dynamics after BICEP2 and PLANCK dust polarisation data
Kaushik Bhattacharya, Joydeep Chakrabortty, Suratna Das +1
If the recent detection of mode polarization of the Cosmic Microwave Background by BICEP2 observations, withstand the test of time after the release of recent PLANCK dust polar…
Classicalization of inflationary perturbations by collapse models in the light of BICEP2
Suratna Das, Satyabrata Sahu, Shreya Banerjee +1
Inflationary and hence quantum origin of primordial perturbations is on a firmer ground than ever post the BICEP2 observations of primordial gravitational waves. One crucial ingred…
