摘要
Weak-coupling perturbation series are calculated for the Hamiltonian version of compact U(1) lattice gauge theory in D + 1 dimensions. Expansions are obtained for the ground-state energy density and its finite-size corrections, the dispersion relation and photon velocity, and the axial string tension on a finite lattice. The finite-size scaling behavior can be simply understood on the basis of an effective Lagrangian which is that of free electromagnetic theory.
