Abstract

The spectrum of a quantum Ising model with staggered interaction is solved exactly for periodic, antiperiodic and free boundary conditions. The properties of the ground state and the excitation spectrum are investigated at the phase transition points, and the conformal theory and the finite size scaling hypothesis are tested along the critical line. The conformally invariant Hamiltonian is found to be independent of the staggering field in the finite size scaling limit.
