Partially Thermalized eV-Scale Sterile Neutrinos in Dynamical Dark Energy and Non-Flat Cosmologies
Gopal Kashyap, Kanhaiya Lal Pandey
We investigate cosmological constraints on a neutrino framework containing an additional partially thermalized, eV-scale sterile neutrino alongside the three active species…
Phase-Sensitive Heterodyne Detection of MW using EIT Harmonics in Rydberg Atoms
Mangesh Bhattarai, Rishav Hui, Sumanta Khan +3
We investigate the generation and characterization of higher-order harmonics in the probe-laser absorption arising from nonlinear interactions in an electromagnetically induced tra…
Narrow-line cooling of Rb using 5S 6P open transition at 420 nm
Rajnandan Choudhury Das, Dangka Shylla, Arkapravo Bera +1
Magneto-optical trap (MOT) at narrow (weak) transition offers lower temperature and hence is the key for production of high phase density atomic cloud and subsequently quantum dege…
Formation and Abundance of Late Forming Primordial Black Holes as Dark Matter
Amlan Chakraborty, Prolay K Chanda, Kanhaiya Lal Pandey +1
We propose a novel mechanism where Primordial Black Hole (PBH) dark matter is formed much later in the history of the universe between the epoch of Big Bang Nucleosynthesis (BBN) a…
Implications of an extended dark energy model with massive neutrinos
Ravi Kumar Sharma, Kanhaiya Lal Pandey, Subinoy Das
Recently there has been reports of finding a lower bound on the neutrino mass parameter () when using ACT and SPTpol data however these bounds on the are still weaker…
Homodyne detection of a two-photon resonance assisted by cooperative emission
Chetan Sriram Madasu, Chang Chi Kwong, David Wilkowski +1
Focusing on the transient regime, we explore atomic two-photon spectroscopy with self-aligned homodyne interferometry in a -system with large optical depth. The two light source…
