Excitations in the chiral spin liquid

Recently, a spin-Hamiltonian was presented [Schroeter et al, Phys. Rev. Lett. \textbf{99}, 097202 (2007)] for which the chiral spin liquid is the exact ground state. This poster will present a numerical study of the excitations of the model, including results obtained by exact diagonalization of the model on 16 and 25-site lattices.
