The mother of all states of the kagome quantum antiferromagnet
Hitesh J. Changlani, Dmitrii Kochkov, Krishna Kumar +2
Frustrated quantum magnets are a central theme in condensed matter physics due to the richness of their phase diagrams. They support a panoply of phases including various ordered s…
Numerical evidence for a chiral spin liquid in the XXZ antiferromagnetic Heisenberg model on the kagome lattice at magnetization
Krishna Kumar, Hitesh J. Changlani, Bryan K. Clark +1
We perform an exact diagonalization study of the spin- XXZ Heisenberg antiferromagnet on the kagome lattice at finite magnetization with an emphasis on the X…
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…
Chern-Simons theory of the magnetization plateaus of the spin-1/2 quantum XXZ Heisenberg model on Kagome Lattice
Krishna Kumar, Kai Sun, Eduardo Fradkin
Frustrated spin systems on Kagome lattices have long been considered to be a promising candidate for realizing exotic spin liquid phases. Recently, there has been a lot of renewed…
