Text of Abstract
The colloidal glass transition has been a challenging task for researchers for the past few decades, owing primarily to the divergence of the timescales near the jamming transition. Furthermore, colloidal systems exhibit aging; the system continuously relaxes over time at high densities and complete arrest may not be reached. In this work, we aim at identifying the microscopic mechanism for the glassy arrest and its connection with the aging phenomenon manifested by these systems. This poster presents a detailed study of the colloidal glass transition using large-scale Stokesian dynamics simulations. We perform well-controlled volume fraction jumps from an equilibrated liquid state to the glassy state with different quench depths up to random-close packing and aging times. In addition, the evolution of the mechanical and structural properties is used to unravel the effect of many-body hydrodynamic forces and lubrication on the glass transition which have been poorly understood.
