摘要：We examine the entanglement properties of the Yang-Mills theory by calculating a entanglement entropy with a = 2 using a SU(3) quenched lattice gauge simulation both in the confinement and the deconfinement phases. In the confinement phase, the derivative of the a entropy with respect to the size l of the subregion, whose entanglement properties are interested in, scales as 1=l3, and a clear discontinuity cannot be found within our statistical errors. The a entropy in the deconfinement phase saturates at large l. The saturation value is comparable with the thermal entropy of the pure Yang-Mills theory, indicating that the a entropy obeys the volume law at large l in the deconfinement phase.
