  Neutrino emission and their transport of energy to the supernova shock region
are sensitive to the physics of hot and dense nuclear matter, which is a
complex problem due to the strong correlations induced by nuclear forces. We
derive charged-current opacities for electron neutrinos and antineutrinos in
supernova matter using a self-consistent approach based on the Skyrme effective
interaction. We include a mean field energy shift due to nuclear interaction
and corrections due to RPA correlations. A complete treatment of the full
Skyrme interaction, including a spin-orbit term, is given. To test the effect
of RPA corrections, neutrino and antineutrino opacities are computed using
different Skyrme parametrizations consistent with a number of infinite matter
constraints.
