A theoretical investigation of quantum‐transport phenomena in mesoscopic systems is presented. In particular, a generalization to “open systems” of the well‐known semiconductor Bloch equations is proposed. Compared to the conventional Bloch theory, the presence of spatial boundary conditions manifests itself through self‐energy corrections and additional source terms in the kinetic equations, which are solved by means of a generalized Monte Carlo simulation. The proposed numerical approach is applied to the study of quantum‐transport phenomena in double‐barrier structures.
