    • To check the validity of our INS simulations, we examined systems, for which exact theoretical results are known. For example, by standard extrapolations to the infinite chain, we obtained the spin gap Δ=0.53 (3) J for the isotropic two-leg spin ladder, which should be compared with the exact value Δ=0.51 J (Ref.), and the correct evolution of the spin gap for the J1 - J2 frustrated chain as a function of α= J2 / J1 (Ref.). We have also checked that the simulated Q dependence of the first excited state satisfactorily describes the structure factor of the spin 1/2 Heisenberg chain.
