Dynamic properties of quasi-confined colloidal hard-sphere liquids near the glass transition — •Lukas Schrack, Charlotte Petersen, and Thomas Franosch — Institut für Theoretische Physik, Universität Innsbruck, Technikerstraße 21A, 6020 Innsbruck, Austria

The complex behavior of confined fluids arising due to a competition between layering and local packing can be disentangled by considering quasi-confined liquids with translational invariance along the confined direction. We provide a mode-coupling theory (MCT) for quasi-confined liquids using multiple relaxation channels and elaborate an efficient method for the numerical implementation.

Investigating both the collective and tagged-particle motion near the glass transition we focus on the non-monotonic behavior of the glass-form factor as well as of the intermediate scattering functions comparing numerical MCT results and simulations. We also provide a non-equilibrium state diagram as a function of the confinement length.
