Neutrino scattering from hydrodynamic modes in hot and dense neutron matter
Neutrino scattering from hydrodynamic modes in hot and dense neutron matter
We calculate the scattering rate of low-energy neutrinos in hot and dense neutron matter encountered in neutrons stars and supernovae in the hydrodynamic regime. We find that the Brillouin peak, associated with the sound mode, and the Rayleigh peak, associated with the thermal diffusion mode, dominate the dynamic structure factor. …
