Hot Brownian Dynamics in Structured Optical Confinement

量子物理学・ナノサイエンス第410回セミナー

概要

Microscopic colloids are basic building blocks of soft and biological matter. They also serve as experimental test beds of Brownian dynamics. By illuminating light-absorbing colloids with a laser beam, one can observe the so-called 'hot-Brownian motion'. This out-of-equilibrium system can form unconventional assemblies and exhibit evolutionary dynamics that can emulate some natural systems. In this talk, I will show how structured optical potentials can influence the assembly, rotation, revolution and synchronization of hot Brownian colloids. I will conclude with a discussion on the interaction of optical vortices with hot Brownian colloids.
