Michael Baro, Hans-Christoph Kaiser, Hagen Neidhardt, and Joachim Rehberg A quantum transmitting Schroedinger-Poisson system (696K, pdf) ABSTRACT. We consider a stationary Schroedinger-Poisson system on a bounded interval of the real axis. The Schroedinger operator is defined on the bounded domain with transparent boundary conditions. This allows to model a non-zero current flow trough the boundary of the interval. We prove that the system always admits a solution and give explicit a priori estimates for the solutions.
