Chiral spin liquids on the kagome Lattice
Krishna Kumar, Kai Sun, Eduardo Fradkin
We study the nearest neighbor Heisenberg quantum antiferromagnet on the kagome lattice. Here we consider the effects of several perturbations: a) a chirality term, b) a Dzyal…

A discretized Chern-Simons gauge theory on arbitrary graphs
Kai Sun, Krishna Kumar, Eduardo Fradkin
In this paper, we show how to discretize the abelian Chern-Simons gauge theory on generic planar lattices/graphs (with or without translational symmetries) embedded in arbitrary 2D…
