Effect of disorder on the ground-state properties of graphene
R. Asgari, M. M. Vazifeh, M. R. Ramezanali +2
We calculate the ground-state energy of Dirac electrons in graphene in the presence of disorder. We take randomly distributed charged impurities at a fixed distance from the graphe…
Theory of the Pseudospin Resonance in Semiconductor Bilayers
Saeed H. Abedinpour, Marco Polini, A. H. MacDonald +3
The pseudospin degree of freedom in a semiconductor bilayer gives rise to a collective mode analogous to the ferromagnetic resonance mode of a ferromagnet. We present a theory of t…
Comparative study of screened inter-layer interactions in the Coulomb drag effect in bilayer electron systems
R. Asgari, B. Tanatar, B. Davoudi
Coulomb drag experiments in which the inter-layer resistivity is measured are important as they provide information on the Coulomb interactions in bilayer systems. When the layer d…
Effective mass enhancement in two-dimensional electron systems: the role of interaction and disorder effects
R. Asgari, B. Davoudi, B. Tanatar
Recent experiments on two-dimensional (2D) electron systems have found a sharp increase in the effective mass of electrons with decreasing electron density. In an effort to underst…
Tunneling properties of quantum dot arrays in strong magnetic field
A. Aldea, V. Moldoveanu, B. Tanatar
We develop a formalism suitable for the study of transport properties of coherent multiple dots which captures and explains the experimentally observed features in terms of spectra…
