Colloidal suspensions under external control

In this thesis, we developed ideas to control the structure and the dynamics of colloidal suspensions by manipulating the boundary conditions and applying external elds. The aforementioned manipulations of colloidal uids not only provide opportunities to improve our understanding of fundamental physical phenomena, but also initiate ideas for developing advanced materials. External control over colloidal suspensions with hard-sphere like interactions -arguably the simplest model system for soft matter studies- can be evoked to tune the interplay between structure and dynamics for both equilibrium and out-of-equilibrium systems. Interplay between structure and dynamics is commonly encountered in Soft Matter systems including but not limited to colloidal suspensions, emulsions, polymers, polyelectrolydes and proteins.
