Dark photon -- Assisted Primordial Magnetogenesis
Debottam Nandi, Debajyoti Choudhury
Magnetic fields observed across cosmic scales are difficult to explain within conventional physics. A primordial origin is, thus, often assumed. While a nonminimal coupling of the…

Sub-Horizon Amplification of Curvature Perturbations: A New Route to Primordial Black Holes and Gravitational Waves
Debottam Nandi, Rohan Roy, Simran Yadav +1
The enhanced primordial scalar power spectrum is a widely studied mechanism for generating primordial gravitational waves (PGWs), also referred to as scalar-induced gravitational w…
