Abstract | The excitation spectrum of the antiferromagnetic spin-1/2 Heisenberg Hamiltonian H=tsumJSj on L×L lattices is evaluated by a projector quantum Monte Carlo method. These results suggest that the exact spectrum for the finite lattice is ωZ(L)ωkSW, for all k, where ωkSW=4JS 1-γk2 with γk=(coskx+cosky)/2 is from linear-spin-wave theory. We find Z(L)=ZE+B/L3, leading to ZE=1.21±0.03 for L=. A comparison with experiments on La2CuO4 is discussed. © 1992 The American Physical Society. |
