Extreme points of the set of density matrices with positive partial transpose
Jon Magne Leinaas, Jan Myrheim, Eirik Ovrum
We present a necessary and sufficient condition for a finite dimensional density matrix to be an extreme point of the convex set of density matrices with positive partial transpose…

Explicit mapping between a 2D quantum Hall system and a 1D Luttinger liquid. II. Correlation functions
Mats Horsdal, Jon Magne Leinaas
We study a simple model of a quantum Hall system with the electrons confined to a linear, narrow channel. The system is mapped to a 1D system which in the low-energy approximation…
