Description
We have studied the mass spectrum and phase structure of compact electrodynamics in D = 2+1 dimensions using the finite-lattice Hamiltonian approach. The numerical results are generally comparable to, but not significantly better than, available strong-coupling series results. Evidence for roughening of the ''on-axis'' string is found at g2 = e2aapprox. =1.5 while the vacuum and glueball sectors of the theory are smooth for all attainable g2 (> or approx. =0.08). Comparisons with results from applying weak-coupling approximations to the theory are also presented
