摘要: We search for broken symmetry in the ground state of spin-1/2 Heisenberg antiferromagnet on a kagome$iaa\char22{} lattice. Specifically, we calculate magnetic, spin-Peierls, spin-nematic, and chiral correlation functions states clusters 9, 12, 15, 18 sites. All four fall rapidly with distance. An analysis their system-size dependence suggests that this model is probably spin liquid full Hamiltonian.
