小系统中的非平衡涨落:从物理学到生物学

Nonequilibrium fluctuations in small systems: From physics to biology

F. Ritort

摘要:

在这篇论文中,我将对与小系统中的非平衡涨落有关的几个主题进行概述。我开始一般性的讨论波动定理和应用程序提取的物理和生物学的例子:一个珠子在光学陷阱和单分子力的实验。接下来,我提出了一个一般性的讨论路径热力学和考虑分布的工作/热波动作为大偏差函数。然后,我从非平衡波动的角度来讨论玻璃态动力学的主题,由于小的合作重排区域。最后,我对未来的前景做了一个简短的题外话。

英文摘要:

In this paper I am presenting an overview on several topics related to nonequilibrium fluctuations in small systems. I start with a general discussion about fluctuation theorems and applications to physical examples extracted from physics and biology: a bead in an optical trap and single molecule force experiments. Next I present a general discussion on path thermodynamics and consider distributions of work/heat fluctuations as large deviation functions. Then I address the topic of glassy dynamics from the perspective of nonequilibrium fluctuations due to small cooperatively rearranging regions. Finally, I conclude with a brief digression on future perspectives.
