Transport through a quantum ring, a dot and a barrier embedded in a nanowire in magnetic field
Vidar Gudmundsson, Yu-Yu Lin, Chi-Shung Tang +3
We investigate the transport through a quantum ring, a dot and a barrier embedded in a nanowire in a homogeneous perpendicular magnetic field. To be able to treat scattering potent…
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…
Swift Identification of Dark Gamma-Ray Bursts
P. Jakobsson, J. Hjorth, J. P. U. Fynbo +4
We present an optical flux vs. X-ray flux diagram for all known gamma-ray bursts (GRBs) for which an X-ray afterglow has been detected. We propose an operational definition of dark…
An optical time delay for the double gravitational lens system FBQ 0951+2635
P. Jakobsson, J. Hjorth, I. Burud +3
We present optical R-band light curves of the double gravitationally lensed quasar FBQ 0951+2635 from observations obtained at the Nordic Optical Telescope between March 1999 and J…
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…
The line-of-sight towards GRB 030429 at z = 2.66: Probing the matter at stellar, galactic and intergalactic scales
P. Jakobsson, J. Hjorth, J. P. U. Fynbo +21
We report the discovery of the optical afterglow (OA) of the long-duration gamma-ray burst GRB 030429, and present a comprehensive optical/near-infrared dataset used to probe the m…
