论文摘要
我们研究了joule-thomson在爱因斯坦 - 马克斯韦（Einstein-Maxwell）理论中的扩展，这些理论补充了所谓的准学电磁学，这是在扩展相空间热力学方法中的。我们计算焦耳thomson系数，并在温度压力平面中描述所有相关的反转和静脉曲线，以这种方式确定相应的冷却和加热区。与以前的相关作品相反，我们显示了反转曲线的三个分支的存在，这些分支取决于理论的参数空间的适当选择，从而脱离了通常的范德华行为，该行为表现出多达两个分支。
We study the Joule-Thomson expansion in Einstein-Maxwell theory supplemented with the so-called quasitopological electromagnetism, this in the extended phase space thermodynamic approach. We compute the Joule-Thomson coefficient and depict all relevant inversion and isenthalpic curves in the temperature-pressure plane, determining in this manner the corresponding cooling and heating regions. In contrast with previous related works we show the existence of three branches for the inversion curves which depends on suitable selections of the parameter space of the theory, thus departing from the usual van der Waals behavior which exhibits up to two branches.
