Abstract
Brownian Motion
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.
