近年来，全球转动下物质的相态和性质引起了人们的广泛兴趣。在这封信中，我们研究了费米子系统在旋转存在下的配对现象。我们发现，有一个通用的抑制效应对零角动量的配对状态。我们以热致密QCD物质中的手征凝聚和色超导性为例证明了这种效应。在手性凝聚的情况下，在温度-转动参数空间中发现了一个新的相图，具有非平凡的临界点。
The phases and properties of matter under global rotation have attracted much interest recently. In this Letter we investigate the pairing phenomena in a system of fermions under the presence of rotation. We find that there is a generic suppression effect on pairing states with zero angular momentum. We demonstrate this effect with the chiral condensation and the color superconductivity in hot dense QCD matter as explicit examples. In the case of chiral condensation, a new phase diagram in the temperature-rotation parameter space is found, with a nontrivial critical point.
