[Pre-synopsis seminar] Response of 2d dense model liquids to a random external potential

Though disordered objects are so ubiquitous in nature and found use in the hands of hominids from the time immemorial, precise scientific principles behind their strange and yet practical behaviour continues to evade our comprehension. Two dimensional versions of disordered systems are studied for the peculiar behaviours specific to this spatial dimension, and also for the experimental ease in handling them. The additional presence of quenched disorders makes the study of these systems exciting. In this talk, we will be initially discussing the melting scenario in 2D, with a spatially random disorder background potential, acting as a quenched disorder in the system. Impact of the background potential and size disparity in the melting scenario will be discussed. This will be followed by a discussion on the effect of such a potential on the route to glass formation. Finally, we will be discussing the scenario when the background potential is varying with time.
