本文研究了有效圈量子宇宙学（LQC）中表观视界的热力学一致性。通过保留视界热力学量的标准定义，我们发现修正的LQC动力学导致偏离经典平衡热力学描述。这种偏差可以自然地由一种以内部熵产生项为特征的非平衡表述来描述。由此产生的熵产生一致地恢复了经典极限和德西特极限。这些结果表明，有效LQC中的表观视界具有一致的非平衡热力学解释。
英文摘要
In this work, we investigate the thermodynamic consistency of the apparent horizon in effective loop quantum cosmology (LQC). By retaining the standard definitions of horizon thermodynamic quantities, we find that the modified LQC dynamics leads to a departure from the classical equilibrium thermodynamic description. This deviation can be naturally described by a nonequilibrium formulation characterized by an internal entropy production term. The resulting entropy production consistently recovers the classical and de Sitter limits. These results suggest that the apparent horizon in effective LQC admits a coherent nonequilibrium thermodynamic interpretation.
