"Short timescale Brownian motion and applications"

2:00pm, RLM 11.204

Abstract: I will report our studies on short timescale Brownian motion of optically-trapped microspheres. We have provided an accurate test of the Maxwell-Boltzmann distribution and energy equipartition theorem for a particle in liquid. We have reported high-bandwidth, comprehensive measurements of boundary effects on Brownian motion imposed by an approximately flat wall. In addition, I will briefly discuss the applications of using Brownian particles as probes to study viscoelasticities of complex fluids, boundary conditions at solid-fluid interfaces, and fluids’ compressibility.
