Gary A. Williams

Gary A. Williams is a Professor of Physics at UCLA, specializing in low-temperature physics. His recent experimental and theoretical work has been concerned with the role of quantized vortices in the superfluid phase transition, particularly for thin helium films adsorbed in porous materials and on nanotubes, and a further line of research has studied the luminescence emitted by collapsing laser-induced bubbles in liquid nitrogen and other liquids. He was named an Outstanding Referee by the American Physical Society in 2008.

Imaging and tracking of bubbles in liquid helium formed by individual electrons allows study of superfluid vortices, and may permit analysis of unusual ionic species in fluids.
