Fluctuation theorems in general relativistic stochastic thermodynamics
Abstract
Based on the recently proposed framework of general relativistic stochastic mechanics [ J. Stat. Phys., 190:193, 2023; J. Stat. Phys., 190:181, 2023] and stochastic thermodynamics [ SciPost Physics Core 7, 082, 2024] at the ensemble level, this work focuses on general relativistic stochastic thermodynamics at the trajectory level. The first law of stochastic thermodynamics is reformulated and the fluctuation theorems are proved on this level, with emphasis on maintaining fully general covariance and on the choice of observers.
