We consider the quantum melting of a two-dimensional flux lattice at temperature (Formula presented) in the "superclean limit." In this regime, we find that vortex motion is dominated by the Magnus force. A Lindemann criterion predicts melting when (Formula presented), where (Formula presented) and (Formula presented) are the areal number densities of vortex pancakes and Cooper pairs, and (Formula presented). A second criterion is derived by using Wigner-crystal and Laughlin wave functions for the solid and liquid phases respectively, and setting the two energies equal. This gives a melting value similar to the Lindemann result. We discuss the numerical value of the (Formula presented) melting field for thin layers of a low-(Formula presented) superconductor, such as (Formula presented)-MoGe, and single layers of high-(Formula presented) materials.
