最近有人提出纠缠熵可以作为禁闭/解除禁闭跃迁的序参量。为了找到一个明确的证据，我们引入了一个新的量，称为几何熵，它是通过一个双威克旋转的纠缠熵。我们分析了几何熵，明确地表明在自由= 4的超杨-米尔斯体系和它的超引力对偶体系中，几何熵在哈格多恩温度下变得不连续。
It has recently been proposed that the entanglement entropy can be an order parameter of confinement/deconfinement transitions. To find a clear evidence, we introduce a new quantity called the geometric entropy, which is related to the entanglement entropy via a double Wick rotation. We analyze the geometric entropy and manifestly show that its value becomes discontinuous at the Hagedorn temperature both in the free = 4 super Yang-Mills and in its supergravity dual.
