Multi-mode transport through a quantum nanowire with two embedded dots
Vidar Gudmundsson, Gudny Gudmundsdottir, Jens Hjorleifur Bardarson +3
We investigate the conductance of a quantum wire with two embedded quantum dots using a T-matrix approach based on the Lippmann-Schwinger formalism. The quantum dots are represente…
Coherent electronic transport in a multimode quantum channel with Gaussian-type scatterers
Jens Hjorleifur Bardarson, Ingibjorg Magnusdottir, Gudny Gudmundsdottir +3
Coherent electron transport through a quantum channel in the presence of a general extended scattering potential is investigated using a T-matrix Lippmann-Schwinger approach. The f…
Magnetization of noncircular quantum dots
Ingibjorg Magnusdottir, Vidar Gudmundsson
We calculate the magnetization of quantum dots deviating from circular symmetry for noninteracting electrons or electrons interacting according to the Hartree approximation. For fe…
Influence of shape of quantum dots on their far-infrared absorption
Ingibjorg Magnusdottir, Vidar Gudmundsson
We investigate the effects of the shape of quantum dots on their far-infrared absorption in an external magnetic field by a model calculation. We focus our attention on dots with a…
The far-infrared absorption of a periodic 2DEG in the transition regime between weak and strong modulation
Vidar Gudmundsson, Ingibjorg Magnusdottir, Sigurdur I. Erlingsson
We study the optical absorption of arrays of quantum dots and antidots in a perpendicular homogeneous magnetic field. The electronic system is described quantum mechanically using…
