reveals that a single component fluid can undergo glass-like dynamics due to confinement.
The self intermediate scattering function, of the confined fluid
exhibits a two step relaxation at moderate temperatures and follows
the time-temperature superposition principle observed in bulk glass formers.
The self-diffusivity and relaxation times of the confined fluid are found to follow scalings
predicted by mode coupling theories developed for bulk glass formers.
The system exhibits a crossover temperature which is above the glass transition temperature.
At lower temperatures, signatures of additional relaxation processes are observed in the various
dynamical quantities with the self-intermediate scattering function relaxing in three steps.
The temperature dependence of the self-diffusivity can be accurately expressed
by the Vogel-Fulcher-Tammann equation and the fluid can be classified as
a fragile glass former based on the fragility index. Simulations are carried out for
pore spacings that can accommodate one to four fluid layers and the influence of the
confining surface (structured or smooth) on the glassy dynamics is explored.
