Description

We demonstrate that with a stepwise introduction of complexity to a model of an electron system embedded in a photonic cavity and a carefully controlled stepwise truncation of the ensuing many-body space it is possible to describe the time-dependent transport of electrons through the system with a non-Markovian generalized quantum master equation. We show how this approach retains effects of the geometry of an anisotropic electronic system. The Coulomb interaction between the electrons and the full electromagnetic coupling between the electrons and the photons are treated in a non-perturbative way using "exact numerical diagonalization". We will elucidate how the sequential tunneling of electrons in and out of the system is influenced by the symmetry of their wavefunctions and spin structure, i.e. how correlation effects shape the dynamic transport properties of these few electron systems.
