报告摘要：

Work and heat, as two fundamental quantities in thermodynamics, become stochastic variables when entering the microscopic world. When a microscopic open system is driven out of equilibrium, the joint distribution of work and heat, compared to the marginal distributions, encode more information about the nonequilibrium processes, including the irreversibility and the fluctuation. For driven open systems coupled to multiple heat baths, we find a hierarchical structure of fluctuation theorems for the joint distribution of work and heat. These fluctuation theorems extend the well-known Jarzynski equality and Crooks fluctuation theorems from the situation of a single heat bath to that of multiple heat baths, and are derived in both the classical and the quantum setups. We also propose a general method to calculate the joint distributions of work and heat via the Feynman-Kac equation. For the classical Brownian motion model, we verify the validity of the fluctuation theorems with the joint distribution of work and heat.
