title: Theoretical and experimental investigations of Coulomb blockade in coupled quantum dot systems.
abstract: Two strongly coupled quantum dots are theoretically and experimentally investigated. In conductance measurements on a GaAs based low-dimensional system additional features to the Coulomb blockade have been detected at low temperatures. These regions of finite conductivity are compared with theoretical investigations of a strongly coupled quantum dot system and good agreement between the theoretical and the experimental results has been found.
