介子与准正规模：过冷和过热
Mesons versus quasi-normal modes: undercooling and overheating
摘要：
在有物质的全息规范理论模型中，普遍存在介子离解的一级相变。我们分别对过热区的介子谱和准粒子谱进行了细致的分析。过冷区接近两相的交界处。我们表明，所有过热的有限介子质量最终成为无限简并，这意味着任何准粒子谱的连接是比以前提出的更微妙。对于Sakai-Sugimoto模型，这些光谱之间没有平滑的连接是可能的。
英文摘要：
In holographic models of gauge theories with matter, there generically exists a first order phase transition in which mesons dissociate. We perform a careful analysis of the meson and quasi-particle spectra in the overheated resp. undercooled regimes close to the junction of the two phases. We show that all overheated finite meson masses eventually become infinitely degenerate, which implies that any connection to the quasi-particle spectrum is more subtle than previously suggested. For the Sakai-Sugimoto model no smooth connection between these spectra is possible.
