Fermi liquids and fractional statistics in one dimension
Jon Magne Leinaas
Interacting fermion systems in one dimension, which in the low energy approximation are described by Luttinger liquid theory, can be reformulated as systems of weakly interacting p…
Luttinger liquids, Fermi liquids and fractional statistics
Jon Magne Leinaas
We discuss how one-dimensional interacting fermion systems, which in the low energy approximation are described by Luttinger liquid theory, can be reformulated as systems of weakly…
The Quantum Torus Chain
M. P. Qin, J. M. Leinaas, S. Ryu +3
We introduce a new set of one dimensional quantum lattice models which we refer to as The quantum torus chain. These models have discrete global symmetry, and projective on-site re…
Unextendible product bases and extremal density matrices with positive partial transpose
Per Øyvind Sollid, Jon Magne Leinaas, Jan Myrheim
In bipartite quantum systems of dimension 3x3 entangled states that are positive under partial transposition (PPT) can be constructed with the use of unextendible product bases (UP…
Charge Fractionalization on Quantum Hall Edges
Mats Horsdal, Marianne Rypestøl, Hans Hansson +1
We discuss the propagation and fractionalization of localized charges on the edges of quantum Hall bars of variable widths, where interactions between the edges give rise to Luttin…
Low rank extremal PPT states and unextendible product bases
Jon Magne Leinaas, Jan Myrheim, Per Øyvind Sollid
It is known how to construct, in a bipartite quantum system, a unique low rank entangled mixed state with positive partial transpose (a PPT state) from an unextendible product basi…
