Proton energy relaxation in an electron gas in a uniform magnetic field

Abstract

Energy relaxation of single protons in an ultracold electron gas in the presence and absence of a uniform magnetic field is studied by the method of molecular dynamics. For the case with a magnetic field, the situation is considered in which the electron Larmor radius is much smaller than the classical minimal approach distance. The calculations are performed for electron densities of 10⁸–10⁹ cm^–3, magnetic fields of В = 1–3 T, electron temperatures of 10–50 K, and proton energies of 100–300 000 K.
