论文摘要
我们在Witten-Sakai-Sugimoto模型中指出了一种新的配置，允许在尖端近似中的重子与基本夸克共存。最终的阶段是对夸克的全息实现，预计在QCD中以许多颜色发生在QCD中，并且可能在现实世界中也起作用。我们发现全息夸张的物质是手性在对称的，并且对于大型的重子化学电位，它在纯核物质上和纯夸克物质上是能量优先的。从核物质到Quarkyonp阶段的零温度过渡是在手性极限和逼真的锥度质量中的一阶。对于远远超出物理点的pion质量，我们观察到由于存在夸克物质而导致的夸克 - 哈德隆连续性。
We point out a new configuration in the Witten-Sakai-Sugimoto model, allowing baryons in the pointlike approximation to coexist with fundamental quarks. The resulting phase is a holographic realization of quarkyonic matter, which is predicted to occur in QCD at a large number of colors, and possibly plays a role in real-world QCD as well. We find that holographic quarkyonic matter is chirally symmetric and that, for large baryon chemical potentials, it is energetically preferred over pure nuclear matter and over pure quark matter. The zero-temperature transition from nuclear matter to the quarkyonic phase is of first order in the chiral limit and for a realistic pion mass. For pion masses far beyond the physical point we observe a quark-hadron continuity due to the presence of quarkyonic matter.
