摘要: A new method for investigating the behaviour of lattice Hamiltonian field theories is described. The uses finite-size scaling to extrapolate finite-lattice results infinite chain limit. technique illustrated by application transverse Ising model and (O(N)-Heisenberg Hamiltonians (N=2,3) in (1+1) dimensions. accuracy appears comparable or better than existing approaches.
