Tuning of coupling modes in laterally parallel double open quantum dots
Chi-Shung Tang, Wing Wa Yu, Vidar Gudmundsson
We consider electronic transport through laterally parallel double open quantum dots embedded in a quantum wire in a perpendicular magnetic field. The coupling modes of the dots ar…
The GRB 030329 host: a blue low metallicity subluminous galaxy with intense star formation
J. Gorosabel, D. Pérez-Ramírez, J. Sollerman +13
We present broad band photometry and spectroscopic observations of the host galaxy of GRB 030329. Analysis of the spectral emission lines shows that the host is likely a low metall…
A state with negative binding energy induced by coherent transport in a quantum wire
Vidar Gudmundsson, Chi-Shung Tang, Andrei Manolescu
In a two-dimensional quantum wire in a perpendicular magnetic field with a smooth embedded repulsive scattering potential we find in the multimode conductance resonances caused by…
Ly-alpha and UV emission from high-redshift GRB hosts: To what extent do GRBs trace star formation?
P. Jakobsson, G. Bjornsson, J. P. U. Fynbo +9
We report the result of a search for Ly-alpha emission from the host galaxies of the gamma-ray bursts (GRBs) 030226 (z = 1.986), 021004 (z = 2.335) and 020124 (z = 3.198). We find…
The Siciak-Zahariuta extremal function as the envelope of disc functionals
Finnur Larusson, Ragnar Sigurdsson
We establish disc formulas for the Siciak-Zahariuta extremal function of an arbitrary open subset of complex affine space, generalizing Lempert's formula for the convex case. This…
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…
