摘要：

在零温度下具有大量颜色的致密QCD是一种晶体。我们表明，在全息对偶描述中，晶体是由双子对与$e=g=\pm 1$电荷在盐状安排。我们认为，随着密度的增加，双子质量和拓扑电荷均衡，把盐状配置的bcc的半瞬子。后者是对偶的半skyrmions立方晶体。我们估计从fcc晶体的瞬子到bcc晶体的双子到约3倍的核物质密度的双子结合能约为180 MeV的过渡。

英文摘要：

Dense QCD at zero temperature with a large number of colors is a crystal. We show that in the holographic dual description, the crystal is made out of pairs of dyons with $e=g=\pm 1$ charges in a salt-like arrangement. We argue that with increasing density the dyon masses and topological charges equalize, turning the salt-like configuration to a bcc of half-instantons. The latter is dual to a cubic crystal of half-skyrmions. We estimate the transition from an fcc crystal of instantons to a bcc crystal of dyons to about 3 times nuclear matter density with a dyon binding energy of about 180 MeV.
