Summary

The effect of Coulomb interactions on phase separation is studied in a spin-one lattice gas model which is a coarse-grained representation of the charge distribution in high-temperature superconductors. The ground states are determined for the complete range of parameters by using a combination of numerical and analytical techniques. A crossover from phase separated to Wigner crystalline states proceeds via a rich structure of highly symmetric striped and checkerboard phases. There is no devil’s staircase behavior because mixtures of stripes with different period phase separate.
