标题： Exponential Modification of AdS Black Hole and Thermodynamic Behavior

摘要： 在本文中，我们提出了一个指数修正，用于无物质场情况下AdS黑洞的作用量。 得到了至扰动系数第三阶的近似黑洞解。 在正则系综中的热力学研究显示，该模型中未出现范德瓦尔斯流体的行为。 然而，对热力学势和其他相关量的研究表明，该模型中可以发生一阶和二阶热力学相变。 相变的形式更类似于霍金-佩吉相变。 显示英文摘要

摘要： In this paper, we present an exponential modification for the action of an AdS black hole in the absence of a matter field. An approximated black hole solution is obtained up to the third order of perturbation coefficient. A thermodynamic investigation in canonical ensemble shows that the behavior of a Van der Waals fluid is not seen in this model. Nevertheless, the study of thermodynamic potentials and other related quantities suggests that the thermodynamic phase transitions of the first and second types can occur in this model. The forms of the phase transitions are more similar to the Hawking-Page phase transitions.
