Mesoscopic Transport: The Electron-Gas Sum Rules in a Driven Quantum Point Contact
Mukunda P. Das, Jagdish S. Thakur, Frederick Green
The nature of the electron gas is characterized, above all, by its multi-particle correlations. The conserving sum rules for the electron gas have been thoroughly studied for many…
A central role for the exchange-correlation hole in the 2D metal-insulator transition
D. J. W. Geldart, D. Neilson, J. S. Thakur
The 2D metal-insulator transition can be induced either by decreasing the carrier density or by increasing the spin polarization by applying a magnetic field parallel to the plane.…
Central role of exchange-correlation hole in the 2D metal-insulator
J. S. Thakur, D. Neilson
We show that the metal to insulator transition, whether generated by decreasing the electron density or by increasing the spin alignment, is determined by a universal functional fo…
Destabilization of the 2D conducting phase by an in-plane magnetic field
J. S. Thakur, D. Neilson
We propose a mechanism for the recently reported destabilization by an in-plane magnetic field of the conducting phase of low density electrons in 2D. We apply our self-consistent…
