The theory of Coulomb Drag in Graphene Systems
… two similar problems that combine the theory of Coulomb drag with the emerging field of graphene physics. First, the theory of Coulomb drag between two graphene mono-layers is extended to include finite temperature. It is found that the effect is strongly enhanced at intermediate temperatures by …

Coulomb drag in quantum Hall systems near v = 1/2
… fermion approach for theoretical studies of the Coulomb drag between two parallel layers of two-dimensional electron gases in the quantum Hall regime near Landau level filling fraction v = 1/2. Within the composite fermion approach, we use Boltzmann transport theory to determine the …

Phase coherence in the regime of bilayer exciton condensation
… and holes (i.e., excitons) is mediated by Coulomb interactions. In this thesis this excitonic state was investigated by interlayer tunneling and Coulomb drag experiments. The Coulomb drag experiments on Corbino ring structures have shown a minimum in the conductivity, implying an energy gap …

Transport studies in graphene-based materials and structures
… the counterflow thermoelectric transport and Coulomb drag. In the last we present our theoretical considerations about the transport properties of multilayer systems with interlayer Coulomb interactions, using phenomenological arguments, Drude-like models and Boltzmann transport formalism, and …

One-dimensional bosonization approach to higher dimensions
… edges is obtained, which can be verified in a Coulomb drag experiment. The second part of the dissertation is devoted to quasi-one dimensional antiferromagnetic lattices. A spatially anisotropic lattice antiferromagnet can be viewed as an array of one dimensional spin chains coupled in a way to …
