Abstract

Slow dynamics in an amorphous quasi-two-dimensional complex plasma, comprised of microparticles
of two different sizes, was studied experimentally. The motion of individual particles was observed using
video microscopy, and the self-part of the intermediate scattering function as well as the mean-squared
particle displacement was calculated. The long-time structural relaxation reveals the characteristic behavior
near the glass transition. Our results suggest that binary complex plasmas can be an excellent model system
to study slow dynamics in classical supercooled fluids.
