Active diffusing crystals in a 2D non-equilibrium system
Ashley Z. Guo, Sam Wilken, Dov Levine +1
We investigate a 2D dynamical absorbing state model of monodisperse disks, in which rich phase behavior arises from interactions consisting solely of repulsive displacements betwee…
Dynamical approach to the jamming problem
Sam Wilken, Ashley Z. Guo, Dov Levine +1
A simple dynamical model, Biased Random Organization, BRO, appears to produce configurations known as Random Close Packing (RCP) as BRO's densest critical point in dimension .…
Spatial Organization of Phase-separated DNA Droplets
Sam Wilken, Aria Chaderjian, Omar A. Saleh
Many recent studies of liquid-liquid phase separation in biology focus on phase separation as a dynamic control mechanism for cellular function, but it can also result in complex m…
Sedimentation of a Colloidal Monolayer Down an Inclined Plane
Brennan Sprinkle, Sam Wilken, Shake Karapetyan +7
We study the driven collective dynamics of a colloidal monolayer sedimentating down an inclined plane. The action of the gravity force parallel to the bottom wall creates a flow ar…
Hyperuniform structures formed by shearing colloidal suspensions
Sam Wilken, Rodrigo E. Guerra, David J. Pine +1
In periodically sheared suspensions there is a dynamical phase transition characterized by a critical strain amplitude between an absorbing state where particle trajectories…
Dense Suspension Splat: Monolayer Spreading and Hole Formation After Impact
Luuk A. Lubbers, Qin Xu, Sam Wilken +2
We use experiments and minimal numerical models to investigate the rapidly expanding monolayer formed by the impact of a dense suspension drop against a smooth solid surface. The e…
