In the present work, we have studied the spectrum of the primordial gravitational waves due to magnetic instability in the presence of neutrino asymmetry. The magnetic instability generates a helical magnetic field on a large scale. The anisotropic stress generated by the magnetic field is shown to be a source of primordial gravitational waves at the time of matter-neutrino decoupling. We expect that the theoretically predicted gravitational waves by this mechanism may be detected by the Square… Expand

Generation of magnetic fields and gravitational waves at neutrino decoupling.
We show that an inhomogeneous cosmological lepton number may have produced turbulence in the primordial plasma when neutrinos entered the (almost) free-streaming regime. This effect may beExpand
Chiral plasma instability and primordial gravitational waves
It is known that cosmic magnetic field, if present, can generate anisotropic stress in the plasma and hence, can act as a source of gravitational waves. These cosmic magnetic fields can be generatedExpand
