从纠缠熵的角度研究了存在于双曲空间中的全息超对称杨-米尔斯（SYM）理论。该理论包含一个与SYM理论的激励相对应的参数，它控制着理论的动力学特性。通过施加相对纠缠熵和激发态能量密度的热力学定律，得到了纠缠温度。这个温度在参数的任何值上都是可用的，甚至在霍金温度消失的区域也是如此。在这个新温度下，用热力学定律检验了激发态SYM理论的动力学性质。我们可以找到理论相变的特征。
We study the holographic supersymmetric Yang-Mills (SYM) theory, which is living in a hyperbolic space, in terms of the entanglement entropy. The theory contains a parametercorresponding to the excitation of the SYM theory, and it controls the dynamical properties of the theory. The entanglement temperature,, is obtained by imposing the thermodynamic law for the relative entanglement entropy and the energy density of the excitation. This temperature is available at any value of the parametereven in the region where the Hawking temperature disappears. With this new temperature, the dynamical properties of the excited SYM theory are examined in terms of the thermodynamic law. We could find the signatures of phase transitions of the theory.
