 abstract = {The structure and equilibrium properties of a two-dimensional system of
superconducting vortices in a periodic pinning potential with square
symmetry are studied numerically. For a range of the strength of the
pinning potential, the low-temperature crystalline state exhibits only
one of the two basic periodicities (in the x and y directions) of the
pinning potential. This ``partially pinned″ solid undergoes a
continuous melting transition to a weakly modulated liquid as the
temperature is increased. A spin model, constructed using symmetry
arguments, is shown to reproduce the critical behavior at this
transition.},
