p6 - Chiral Resonating Valence Bonds in the Kagome Antiferromagnet
Sylvain Capponi, V. Ravi Chandra, Assa Auerbach +1
The Kagome Heisenberg antiferromagnet is mapped onto an effective Hamiltonian on the star superlattice by Contractor Renormalization. Comparison of ground state energies on large l…

Effective Spin Couplings in the Mott Insulator of the Honeycomb Lattice Hubbard Model
H-Y. Yang, A. F. Albuquerque, S. Capponi +2
Motivated by the recent discovery of a spin liquid phase for the Hubbard model on the honeycomb lattice at half-filling, we apply both perturbative and non-perturbative techniques…
