摘要
布朗运动浸入细菌浴中的光学捕获胶体的位置统计具有显著的非高斯性。Costantino Di Bello、Rita Majumdar、Édgar Roldán 及其同事(文章编号 2300427)为胶体在稀释细菌浴中的波动建立了一个精确可解的理论,并探讨了其热力学后果。作为理论成果,他们确定了实验人员如何从胶体位置统计的非高斯特征中推断出细菌施加的力的统计(通常无法通过实验获得)。
The statistics of the position of an optically-trapped colloid immersed in a bacterial bath is prominently non-Gaussian. Costantino Di Bello, Rita Majumdar, Édgar Roldán, and coworkers (article number 2300427) develop an exactly-solvable theory for the fluctuations of a colloid in a diluted bacterial bath and explore its thermodynamic consequences. Fruits of their theory, they establish how can experimentalists infer the statistics of the forces exerted by the bacteria (often unaccessible experimentally) from the non-Gaussian features of the statistics of the colloid's position.
期刊介绍:
Annalen der Physik (AdP) is one of the world''s most renowned physics journals with an over 225 years'' tradition of excellence. Based on the fame of seminal papers by Einstein, Planck and many others, the journal is now tuned towards today''s most exciting findings including the annual Nobel Lectures. AdP comprises all areas of physics, with particular emphasis on important, significant and highly relevant results. Topics range from fundamental research to forefront applications including dynamic and interdisciplinary fields. The journal covers theory, simulation and experiment, e.g., but not exclusively, in condensed matter, quantum physics, photonics, materials physics, high energy, gravitation and astrophysics. It welcomes Rapid Research Letters, Original Papers, Review and Feature Articles.
