Abstract
We study the production of electron density waves by neutrinos propagating through a plasma. We treat this process in field theoretically as a Cherenkov emission of phonons (quanta of electron density waves) by neutrinos. The energy transferred to a supernova shock wave by phonon emission from neutrinos is a factor 2 x 102 times the corresponding energy deposited by plasmon (longitudinal photon) emission.
Keywords: Neutrino; supernova; phonon.
