论文摘要
中心数量是工作分布的波动定理是非平衡热力学的重要特征。在这项工作中，基于动作理论的消化方程式，我们开发了一种确切的方法来评估量子杂质系统浴 - 浴混合过程中的工作分布，在存在非马克维亚和强耦合的情况下。我们的结果不仅准确地重现了Jarzynski平等和骗子的关系，而且还揭示了有关大偏差的丰富信息。使用自旋玻色子模型系统进行数值演示。
The fluctuation theorem, where the central quantity is the work distribution, is an important characterization of nonequilibrium thermodynamics. In this work, based on the dissipaton-equation-of-motion theory, we develop an exact method to evaluate the work distributions in quantum impurity system-bath mixing processes, in the presence of non-Markovian and strong couplings. Our results not only precisely reproduce the Jarzynski equality and Crooks relation, but also reveal rich information on large deviation. The numerical demonstrations are carried out with a spin-boson model system.
