Impact of Helical Electromagnetic Fields on the Axion Window
Takeshi Kobayashi, Rajeev Kumar Jain
Primordial electromagnetic fields can strongly affect the cosmic evolution of axions, and vice versa. We show that if helical electromagnetic fields are coherently produced in the…

Small scale induced gravitational waves from primordial black holes, a stringent lower mass bound, and the imprints of an early matter to radiation transition
Nilanjandev Bhaumik, Rajeev Kumar Jain
In all inflationary scenarios of primordial black holes (PBH) formation, amplified scalar perturbations inevitably accompany an induced stochastic gravitational waves background (I…
