Jamming transition and emergence of fracturing in wet granular media
… behind the morphodynamics that govern the transition between different regimes. A modified capillary number characterizes the crossover from capillary fingering to viscous fingering, and a transition from fingering to fracturing can be achieved either by decreasing frictional resistance. …

Unearthing the Anticrystal: Criticality in the Linear Response of Disordered Solids
… temperature that, when compressed, undergos a jamming phase transition with diverging length scales and clean power-law signatures. This critical point is the cornerstone of a much larger ``jamming scenario" that has the potential to provide the essential theoretical foundation that is sorely …

Feedback Control Theory in Stochastic Dynamical Systems
… a study on finite-size effects at the phase transition in the Nagel-Schreckenberg traffic model as an example of non-equilibrium many body stochastic dynamical system. For quantum mechanical model, I introduce an optimal measurement-based feedback control protocol for cooling a single qubit …

Coffee-Rings and Glasses: Colloids Out of Equilibrium
… of particles during evaporation and the glass transition are explored. In the first set of experiments, we found that particle shape has a profound effect on particle deposition. We evaporated drops of colloidal suspensions containing micron-sized particles that range in shape from isotropic …

Development of nanogels from nanoemulsions and investigation of their rheology and stability
… the dispersed phase (eff) close to the random jamming, resulting in repulsive gelation. 2) At SDS concentration between 5 – 15 times CMC, micelle induced depletion attractions led to extensive droplet aggregation and gelation. 3) At very high SDS concentration, however, oscillatory structural …

Study of atomic scale dynamics of glass-forming metallic liquids using neutron scattering experiments and molecular dynamics simulations
… the universality of liquid dynamics and glass-transition. This research aims to quantify the underlying nature of atomic-scale dynamics using experimental neutron scattering techniques and computational molecular dynamics simulations accompanied by machine learning. Specifically, this work …

Rigidity in Frictional Particle Packings and Dynamics in Living Polymeric Packings
… first act encapsulates a study of the rigidity transition in frictional particle packings, or how a packing goes from floppy-to-rigid as its particle density increases, for example. While consensus has emerged regarding the nature of the rigidity transition in frictionless packings, there is …

Rigidity and Fluidity in Living and Nonliving Matter
… do not readily apply to non-equilibrium phase transitions such as the fluid-to-disordered solid transition found in repulsive particulate systems. Examples of repulsive particulate systems are sand grains and colloids. The first part of this thesis contributes to methods beyond equilibrium …
