标题： The Smile of Cheshire Cat At High Density

摘要： 有限核、核物质和致密星物质中的重子可以用QCD的“柴郡猫”描述。 尽管数学严谨性不足，但它们的表现之间存在一种潜在的概念性联系，这就是所谓的“柴郡猫原理”所建立的。 用与QCD变量“对偶”的术语表述，达到极高的密度会暴露出量子霍尔液滴（或薄饼），在这一点上，达到了固定点，其中包含 $g_A\to 1$ 和 $f_\pi\to f_\chi$ ——其中 $f_\pi$ 和 $f_\chi$ 分别为π介子和膨胀子的衰变常数——以及重子的宇称加倍现象。 这一场景暗示了一种迄今为止完全未被探索的高密度下双重重子物质结构，这种结构既不需要也不排除在濒临引力崩塌的致密星核心中从强子到夸克的（快速）一阶相变。 显示英文摘要

摘要： Baryons in finite nuclei, nuclear matter and dense compact-star matter are described in terms of Cheshire Cat for QCD. A potential conceptual link, admittedly short in mathematical rigor, between their manifestations is made by what's called Cheshire Cat Principle. Put in terms taken ``dual" to QCD variables, going to very high density exposes quantum Hall droplets -- or pancakes -- at which the dilaton-limit fixed point with $g_A\to 1$, $f_\pi\to f_\chi$ -- where $f_\pi$ and $f_\chi$ are respectively the pion and dilaton decay constants -- and the baryon parity-doubling are reached. This scenario suggests a thus-far totally unexplored structure of dual baryonic matter at high density which does neither require nor rule out (rapid) first-order phase transitions from hadrons to quarks in the core of compact stars on the verge of gravitational collapse.
