Symmetry, Invariant Manifolds and Flow Reversals in Active Nematic Turbulence
Angel Naranjo, Rumayel Pallock, Caleb Wagner +1
We investigate the role of symmetry, exact coherent structures (ECSs), and their invariant manifolds in organizing flow reversals and turbulent dynamics in channel-confined two-dim…
Exact coherent structures and phase space geometry of pre-turbulent 2D active nematic channel flow
Caleb G. Wagner, Michael M. Norton, Jae Sung Park +1
Confined active nematics exhibit rich dynamical behavior, including spontaneous flows, periodic defect dynamics, and chaotic `active turbulence'. Here, we study these phenomena usi…
Steady states of active Brownian particles interacting with boundaries
Caleb G. Wagner, Michael F. Hagan, Aparna Baskaran
An active Brownian particle is a minimal model for a self-propelled colloid in a dissipative environment. Experiments and simulations show that, in the presence of boundaries and o…
Response of active Brownian particles to boundary driving
Caleb G. Wagner, Michael F. Hagan, Aparna Baskaran
We computationally study the behavior of underdamped active Brownian particles in a sheared channel geometry. Due to their underdamped dynamics, the particles carry momentum a char…
Noise and diffusion of a vibrated self-propelled granular particle
Lee Walsh, Caleb G. Wagner, Sarah Schlossberg +3
Granular materials are an important physical realization of active matter. In vibration-fluidized granular matter, both diffusion and self-propulsion derive from the same collision…
Steady-state distributions of ideal active Brownian particles under confinement and forcing
Caleb G. Wagner, Michael F. Hagan, Aparna Baskaran
We develop a formally exact technique for obtaining steady-state distributions of non-interacting active Brownian particles in a variety of systems. Our technique draws on results…
A classical nucleation theory description of active colloid assembly
Gabriel S. Redner, Caleb G. Wagner, Aparna Baskaran +1
Non-aligning self-propelled particles with purely repulsive excluded volume interactions undergo athermal motility-induced phase separation into a dilute gas and a dense cluster ph…
