A numerical study of the neutral two-dimensional (2D) lattice Coulomb gas is\nperformed to examine dynamic scaling, finite size effects, and the dynamic\ncritical exponent z of the Kosterlitz-Thouless-Berezinskii transition. By\nstudying large system sizes (L=100), we show z=2.0 \±0.2 using\nFisher-Fisher-Huse (FFH) scaling. We also present evidence that the vortex\ncorrelation length is finite below the transition temperature, in contrast to\nconventional wisdom. Finally, we conclude that previous findings for a variety\nof experimental systems that z\≃ 5.6 using FFH scaling indicates that\nfinite size effects are ubiquitous in 2D superconductors and Josephson Junction\nArrays.\n
