论文摘要
我们重新审视了一般相对论中最小耦合的标量场与完美的流体之间的类比,从而纠正了先前对有效温度和化学电位的识别。这为标量调节重力的一阶热力学提供了有用的互补图片,为爱因斯坦框架配方铺平了道路(这是先前尝试的尝试),并提出了有趣的问题以进一步发展类比。
We revisit the analogy between a minimally coupled scalar field in general relativity and a perfect fluid, correcting previous identifications of effective temperature and chemical potential. This provides a useful complementary picture for the first-order thermodynamics of scalar-tensor gravity, paving the way for the Einstein frame formulation (which eluded previous attempts) and raises interesting questions to further develop the analogy.
