摘要:

在随机热力学中,人们对热和功等热力学量的统计行为给予了大量关注。然而,动能和内能等其他量的涨落也可能展现出引人关注的统计性质。在本研究中,我们考察了一个初始处于平衡态的欠阻尼布朗粒子在随后受到同时包含电场和磁场的洛伦兹力作用时,其动能的涨落。我们通过检验特征函数、中心矩以及动能分布来提供相关洞见。

英文摘要:

In stochastic thermodynamics, significant attention has been given to studying the statistical behavior of thermodynamic quantities such as heat and work. However, fluctuations in other quantities, such as kinetic energy and internal energy, can also exhibit intriguing statistical properties. In this study, we investigate the fluctuations of kinetic energy within an initially equilibrated underdamped Brownian particle subsequently exposed to a Lorentz force, comprising both electric and magnetic fields. Providing insights through the examination of the characteristic function, central moments, and kinetic energy distribution.
