Narrow Results

A massive neutrino has nonzero magnetic moment and is involved in the electromagnetic interactions with external fields and photons. The electromagnetic neutrino moving in matter can emit the spin light $(SL\nu )$ in the process of transition between two quantum states in matter. In quite resembling way an electron can emit spin light in moving background composed of neutrinos, that is “the spin light of an electron in neutrino flux” $(SL{e}_{\nu })$. In this paper we obtain the exact solution for the wave function and energy spectrum for an electron moving in a neutrino flux and consider the $SL{e}_{\nu }$ as the transition process between two electron quantum states in the background. The $SL{e}_{\nu }$ radiation rate, power and emitted photon energy are calculated. Notably, the energy spectrum of the emitted $SL{e}_{\nu }$ photons can span up to gamma-rays. We argue that the considered $SL{e}_{\nu }$ can be of interest for astrophysical applications, for supernovae processes in particular.

A massive neutrino has nonzero magnetic moment and is involved in the electromagnetic interactions with external fields and photons. The electromagnetic neutrino moving in matter can emit the spin light (SLν) in the process of transition between two quantum states in matter. In quite resembling way an electron can emit spin light in moving background composed of neutrinos, that is “the spin light of an electron in neutrino flux” (SLe_ν). In this paper we obtain the exact solution for the wave function and energy spectrum for an electron moving in a neutrino flux and consider the SLe_ν as the transition process between two electron quantum states in the background. The SLe_ν radiation rate, power and emitted photon energy are calculated. Notably, the energy spectrum of the emitted SLe_ν photons can span up to gamma-rays. We argue that the considered SLe_ν can be of interest for astrophysical applications, for supernovae processes in particular.
