Annabelle Oz, Oded Hod, Abraham Nitzan

摘要:

利用基于驱动Liouville von-Neumann模型的数值模拟方法研究了驱动共振能级模型的非平衡态热力学。该方法首先验证对最近获得的准静态能级位移和相应的一阶修正的分析结果。数值方法,然后使用有限的水平移动率下的系统的远离平衡态的热力学性质的研究。所提出的方法允许在开放量子系统的未开发的非平衡热力学制度的研究。

英文摘要:

Non-equilibrium thermodynamics of the driven resonant level model is studied using numerical simulations based on the driven Liouville von-Neumann formalism. The approach is first validated against recently obtained analytical results for quasi-static level shifts and the corresponding first order corrections. The numerical approach is then used to study far-from-equilibrium thermodynamic properties of the system under finite level shift rates. The proposed methodology allows the study of unexplored non-equilibrium thermodynamic regimes in open quantum systems.
