Two-Dimensional Vortex Lattice Melting
Jun Hu, A. H. MacDonald
We report on a Monte-Carlo study of two-dimensional Ginzburg-Landau superconductors in a magnetic field which finds clear evidence for a first-order phase transition characterized…
Coulomb Gaps in a Strong Magnetic Field, S.-R
Eric Yang, A. H. MacDonald
We report on a study of interaction effects in the tunneling density-of-states of a disordered two-dimensional electron gas in the strong magnetic field limit where only the lowest…
Coulomb drag between disordered two-dimensional electron gas layers
Lian Zheng, A. H. MacDonald
We derive and evaluate expressions for the frictional Coulomb drag between disordered two-dimensional electron gas layers. Our derivation is based on the memory-function formalism…
Angular Momentum Distribution Function of the Laughlin Droplet
Sami Mitra, A. H. MacDonald
We have evaluated the angular-momentum distribution functions for finite numbers of electrons in Laughlin states. For very small numbers of electrons the angular-momentum state occ…
Quantum Dots in Strong Magnetic Fields: Stability Criteria for the Maximum Density Droplet
A. H. MacDonald, S. -R. Eric Yang, M. D. Johnson
In this article we discuss the ground state of a parabolically confined quantum dots in the limit of very strong magnetic fields where the electron system is completely spin-polari…
