Maximal chirality transfer in the photon-graviton conversion in the early universe
Ashu Kushwaha, Rajeev Kumar Jain
While photons and gravitons do not interact significantly, photons can be converted to gravitons in a background magnetic field -- a phenomenon known as the Gertsenshtein effect. I…

Constraining small-scale primordial magnetic fields from the abundance of primordial black holes
Ashu Kushwaha, Teruaki Suyama
The presence of magnetic fields in the early universe affects the cosmological processes, leading to the distinct signature, which allows constraining their properties and the gene…

Generation and effects of primordial magnetic fields during inflation
Ashu Kushwaha
In this thesis, we aim to investigate the mechanisms underlying the genesis of magnetic fields in the Universe and explore their potential in addressing the matter-antimatter asymm…
