在线性响应区之外,交叉输运中的电流涨落是否有上限?

Is there any upper bound on current fluctuation in cross-transport beyond linear response regime?

Naoto Shiraishi, Tan Van Vu, Keiji Saito

摘要:

研究了具有两种电流的稳态交叉输运系统的输入和输出电流涨落。在Saryal { \it et al.} [Phys. Rev. Lett. 127,190603(2021)],输入和输出电流波动的上限在线性响应机制中得到证明,并建议超出线性响应机制的有效性。我们研究这些界限超出线性响应制度,并发现这些界限是违反一般非平衡平稳条件。我们举两个例子来说明这种违反。通过这些例子,我们认为,输入和输出电流波动的上限不存在超出线性响应制度。

英文摘要:

Input and output current fluctuations in stationary cross-transport systems with two kinds of currents are investigated. In Saryal {\it et al.} [Phys. Rev. Lett. 127, 190603 (2021)], upper bounds on input and output current fluctuations are proven in the linear response regime and suggested the validity beyond the linear response regime. We examine these bounds beyond the linear response regime and find that these bounds are violated in general nonequilibrium stationary conditions. We show two examples to demonstrate the violation. Through these examples, we argue that no upper bound on input and output current fluctuations exist beyond the linear response regime.
