Possible chiral spin liquid state in the S = 1/2 kagome Heisenberg model
Possible chiral spin liquid state in the S = 1/2 kagome Heisenberg model
Abstract The nature of the ground state for the S = 1/2 kagome Heisenberg antiferromagnet (KHAF) has been elusive. We revisit this challenging problem and provide numerical evidence that its ground state might be a chiral spin liquid. Combining the density matrix renormalization group method and analytical analyses, we demonstrate …
