The influence of active agent motility on SIRS epidemiological dynamics
R. Kailasham, Aditya S. Khair
Active Brownian disks moving in two dimensions that exchange information about their internal state stochastically are chosen to model epidemic spread in a self-propelled populatio…
Spontaneous locomotion of a symmetric squirmer
Richard Cobos, Aditya S. Khair, Ory Schnitzer
The squirmer is a popular model to analyse the fluid mechanics of a self-propelled object, such as a micro-organism. We demonstrate that some fore-aft symmetric squirmers can spont…
Effect of speed fluctuations on the collective dynamics of active disks
R. Kailasham, Aditya S. Khair
Numerical simulations are performed on the collective dynamics of active disks, whose self-propulsion speed () varies in time, and whose orientation evolves according to rotatio…
Non-Brownian diffusion and chaotic rheology of autophoretic disks
R. Kailasham, Aditya S. Khair
The dynamics of a two dimensional autophoretic disk is quantified as a minimal model for the chaotic trajectories undertaken by active droplets. Via direct numerical simulations, w…
A multiple-timing analysis of temporal ratcheting
Aref Hashemi, Edward T. Gilman, Aditya S. Khair
We develop a two-timing perturbation analysis to investigate the existence of temporal ratchets in an exemplary system of a particle moving in a tank of fluid in response to an ext…
Dynamics of forced and unforced autophoretic particles
R. Kailasham, Aditya S. Khair
Chemically active, or autophoretic, particles that isotropically emit or absorb solute molecules undergo spontaneous self-propulsion when their activity is increased beyond a criti…
