Abstract: | Influence of the boundary conditions on the finite-size corrections of the one-dimensional (1D) quantum Ising model is analyzed by exact and perturbation theoretic arguments. In this paper we present exact calculations for a new set of universal amplitude ratios in the finite-size correction terms for the 1D quantum Ising model on a finite width strip with free and antiperiodic boundary conditions. The results are in perfect agreement with a perturbated conformal field theory scenario proposed by Cardy [Nucl. Phys. B 270, 186 (1986)]. |
