Numerical Computation Of Two-Dimensional Quantum Spin Liquids In A Kagome Lattice

Materials like pyrochlore and herbertsmithite have shown promising evidence of spin liquid behavior in neutron scattering experiments motivating the study of quantum spin liquids on the two dimensional kagome lattice. Spin liquids have previously been identified in multiple Hamiltonians on the kagome lattice including in the Heisenberg limit. It is an interesting question whether these various spin liquids are part of a single connected phase. Answering this question would further identify an additional class of Hamiltonians which support spin liquids as well as accumulate further evidence about the identity of the S= 1/2 kagome Heisenberg antiferromagnet spin liquid. Using numerical calculations we explore if there is a phase transition between these various spin liquids.
