Skyrme crystal versus Skyrme liquid

摘要: We address the quantum melting phase transition of Skyrme crystal. Based on generic sum rules for two-dimensional, isotropic electron liquids in lowest Landau level, we propose analytic expressions pair-distribution functions spin-polarized and spin-unpolarized liquid phases at filling factors $2/3l~\ensuremath{\nu}l~1.$ From calculate energy such compare with solid phase. The comparison suggests that may lie much closer to $\ensuremath{\nu}=1$ than ever expected.
