Instability of charge ordered states in doped antiferromagnets
Leonid P. Pryadko, Steven Kivelson, Daniel W. Hone
We analyze the induced interactions between localized holes in weakly-doped Heisenberg antiferromagnets due to the modification of the quantum zero point spin wave energy; i.e. the…

Network of edge states: random Josephson junction array description
Leonid P. Pryadko, Karen Chaltikian
We construct a generalization of the Chalker-Coddington network model to the case of fractional quantum Hall effect, which describes the tunneling between multiple chiral edges. We…

Global symmetries of quantum Hall systems: lattice description
Leonid P. Pryadko
I analyze non-local symmetries of finite-size Euclidean 3D lattice Chern-Simons models in the presence of an external magnetic field and non-zero average current. It is shown that…
