双色QCD为有限重子密度下的强相互作用物质提供了一个独特的第一性原理实验室,其中双夸克凝聚实现了重子超流体。我们在手征极限下研究其量子化超流体涡旋的内部物理。我们发现涡旋局域化了一个精确且可归一化的$S^3\simeq SU(2)$介子模式族。值得注意的是,体韦斯-祖米诺-维滕(WZW)项为这些模式诱导了一个量子化的WZW项,从而在红外将涡旋理论驱动到中心荷$c=1$的$SU(2)_1$ WZW共形场论。因此,在非共形体理论中的涡旋上涌现出一个强耦合共形理论。该机制扩展到伪实$Sp(2N)$规范理论,其中相应的最小涡旋理论流向$SU(2)_N$,其能级直接编码微观反常系数。
英文摘要
Two-color QCD provides a unique first-principles laboratory for strongly interacting matter at finite baryon density, where a diquark condensate realizes a baryonic superfluid. We investigate the internal physics of its quantized superfluid vortices in the chiral limit. We find that a vortex localizes an exact and normalizable $S^3\simeq SU(2)$ family of pion modes. Remarkably, the bulk Wess--Zumino--Witten (WZW) term induces a quantized WZW term for these modes, driving the vortex theory in the infrared to the $SU(2)_1$ WZW conformal field theory with central charge $c=1$. Thus a strongly coupled conformal theory emerges on a vortex in a nonconformal bulk theory. The mechanism extends to pseudoreal $Sp(2N)$ gauge theories, where the corresponding minimal vortex theory flows to $SU(2)_N$, with the level directly encoding the microscopic anomaly coefficient.
