Correlated few-electron states in vertical double-quantum-dot systems
Juan Jose Palacios, Pawel Hawrylak
The electronic properties of semiconductor, vertical, double quantum dot systems with few electrons are investigated by means of analytic, configuration-interaction, and mean-field…
Companions of Qsos at Redshift 1.1
J. B. Hutchings, D. Crampton, Andrea Johnson
We discuss broad- and narrow-band imaging of 7 arcmin fields of 14 QSOs with redshift ~1.1. The narrow-band filters were chosen to detect redshifted [O II] 3727A, and the broad ban…
Surveys for Z>1 Field Galaxies; David Crampton
C. L. Morbey, O. Le Fevre, F. Hammer +3
In the course of the comprehensive CFRS redshift survey to I = 22.5 with the CFHT MOS/SIS spectrograph, we have observed ~25 field galaxies with z > 1. However, it is clear that al…
A Gauss-Hermite Expansion of the Galactic Globular Cluster Luminosity Function
Roberto G. Abraham, Sidney Van Den Bergh
We decompose the luminosity function of Galactic globular clusters into a sum of the orthogonal Gauss-Hermite functions. This method quantifies the asymmetric third-order () a…
Possible Metal/Insulator Transition at B=0 in Two Dimensions
S. V. Kravchenko, G. V. Kravchenko, J. E. Furneaux +2
We have studied the zero magnetic field resistivity of unique high- mobility two-dimensional electron system in silicon. At very low electron density (but higher than some sample-d…
Flame propagation in random media
N. Provatas, T. Ala-Nissila, Martin Grant +2
We introduce a phase-field model to describe the dynamics of a self-sustaining propagating combustion front within a medium of randomly distributed reactants. Numerical simulations…
