摘要：

The Hamiltonian limit of the ANNNI model in (1 + 1) dimensions is studied by using the Quantum Statistical Monte Carlo method. Even if recent results suggest that Monte Carlo calculations may prove unreliable in the study of this system, the phase diagram of the quantum version of the model was successfully obtained. In particular, the elusive transitions between the disordered, the floating incommensurate and the degenerate <2,2> are determined by analysing the correlation length behaviour in finite lattices.
