论文摘要
我们通过双重超级重力描述，研究了三维，强烈耦合的杨麦克米尔斯 - 切尔尼 - 西蒙斯野外理论的单参数家族中的各种纠缠措施。这个家庭中的通用田地理论具有质量差距，但没有线性夸克式的潜力。对于参数的两个限制值，理论要么流到固定点或红外线中的限制真空。我们表明，纠缠措施无法区分限制理论与具有质量差距的非限制性措施。这对一个想法提供了支持，即大-N纠缠熵的相变可能仅是由于理论中相当大的规模而引起的，而不应将其本身作为拘留的信号。我们还检查了在中间能量尺度上靠近固定点的流动，发现全息纠缠熵，互信息以及条带和磁盘的F功能与一系列能量范围的共形值匹配。
We study various entanglement measures in a one-parameter family of three-dimensional, strongly coupled Yang-Mills-Chern-Simons field theories by means of their dual supergravity descriptions. A generic field theory in this family possesses a mass gap but does not have a linear quark-antiquark potential. For the two limiting values of the parameter, the theories flow either to a fixed point or to a confining vacuum in the infrared. We show that entanglement measures are unable to discriminate confining theories from non-confining ones with a mass gap. This lends support on the idea that the phase transition of entanglement entropy at large-N can be caused just by the presence of a sizable scale in a theory and just by itself should not be taken as a signal of confinement. We also examine flows passing close to a fixed point at intermediate energy scales and find that the holographic entanglement entropy, the mutual information, and the F-functions for strips and disks quantitatively match the conformal values for a range of energies.
