Abstract

By using the Wigner transform, it is shown that the nonlinear Schro¨\ddot{\textmd{o}}dinger equation can be described, in phase space, by a kinetic theory similar to the Vlasov equation which is used for describing a classical collisionless plasma. In this paper we mainly show Landau damping in the quantum sense, namely,quantum Landau damping exists for the Wigner-Poisson system. At the same time, we also prove the existence and the stability of the nonlinear Schro¨\ddot{\textmd{o}}dinger equation under the quantum stability assumption.
