Nonlinear waves in quantum plasmas
Summary: The study of plasma under extreme conditions of density, such as those found in dense stellar objects or in laser-compression schemes associated with inertial confinement fusion, requires the inclusion of quantum-mechanical and even special-relativistic effects. In particular, the Fermi pre...
