论文摘要

我们通过同时包括旋转和电磁电荷的影响来扩展洛伦兹坚果溶液的热力学的工作。由于Misner Strings具有电荷,并且与非旋转情况相似,因此我们观察到地平线和渐近电荷之间的有趣相互作用。也就是说,在采用欧几里得动作计算后,我们得出了两个替代性完整共同体第一定律,其中一项包括地平线电荷的变化和渐近磁电荷,另一个涉及地平线磁电荷和渐近电荷。当一种地平线电荷消失时,我们获得了通过电磁二元性连接的相应“电”和“磁性”第一定律。我们还简要研究了相应系统的自由能。

We extend the work on thermodynamics of Lorentzian NUTty solutions, by including simultaneously the effect of rotation and electromagnetic charges. Due to the fact that Misner strings carry electric charge, and similar to the non-rotating case, we observe an interesting interplay between the horizon and asymptotic charges. Namely, upon employing the Euclidean action calculation we derive two alternative full cohomogeneity first laws, one that includes the variations of the horizon electric charge and the asymptotic magnetic charge and another that involves the horizon magnetic charge and the asymptotic electric charge. When one of the horizon charges vanishes, we obtain the corresponding "electric" and "magnetic" first laws that are connected by the electromagnetic duality. We also briefly study the free energy of the corresponding system.
