Abstract: In this talk I will first briefly highlight my research on 1)
novel atomic cooling techniques and 2) quantum cellular automata.
Following this introduction, the remainder of the talk will describe my
PhD work on optically trapped microspheres in a natural air environment.
Optically trapped microspheres have recently led the state-of-the-art in
measuring miniscule forces and torques. While their dominance in aqueous
and vacuum environments has been established, their sensitivity to
perturbations in air has remained relatively unexplored. Given this
context, I will describe our trapping and position detection system that
enable resolution of ballistic Brownian motion in air. I will
demonstrate how this system is capable of measuring both inertial mass
and acoustic waves. Brownian motion is present in both measurements, but
its role as signal and noise is interchanged. In addition to describing
these results, I suggest applications of inertial mass sensing to
aerosol science and of sound detection to medical physics and dark
novel atomic cooling techniques and 2) quantum cellular automata.
