论文摘要
在本文中，我们从热力学的角度研究了最近提出的$ f（r，\ natercal {l}）$理论。这些理论的独特性在于一个事实，即时空曲率与重型物质耦合而不是外来物质（以标量场的形式）。我们从模型的热力学稳定性的角度研究了这些理论的生存能力。更确切地说，在这里，我们关注的是Friedmann-Lemaitre-Robertson-Walker（FLRW）时空在$ F（R，\ Mathcal {l}）$理论背景下的热力学。我们考虑了几种$ f（r，\ mathcal {l}）$理论的模型，其中考虑了最小和非最小耦合。计算各种热力学量，例如熵，焓，内部能量，吉布斯自由能等，并使用其允许范围来限制各种模型参数。
In this paper we study the recently proposed $f(R,\mathcal{L})$ theories from a thermodynamic point of view. The uniqueness of these theories lies in the fact that the space-time curvature is coupled to the baryonic matter instead of exotic matter (in the form of scalar field). We investigate the viability of these theories from the point of view of the thermodynamic stability of the models. To be more precise here we are concerned with the thermodynamics of the apparent horizon of Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetime in the background of the $f(R,\mathcal{L})$ theory. We consider several models of $f(R,\mathcal{L})$ theories where both minimal and non-minimal coupling has been considered. Various thermodynamic quantities like entropy, enthalpy, internal energy, Gibbs free energy, etc. are computed and using their allowed ranges various model parameters are constrained.
