Intermediate scattering function of an active Brownian particle
The fundamental element in the field of active matter is the self-propelled particle that transforms free energy from its surroundings into directed motion.These active agents are subject to strong stochastic fluctuations, that compete with their persistent swimming motion. So far most studies consider the lowest order moments of the displacements only, while more general spatiotemporal information is encoded in the directly measurable intermediate scattering function, i.e. the Fourier transform of the probability density. In this talk, I will discuss analytic solutions of the intermediate scattering function of an active Brownian particle, and show, that our theoretical predictions agree very well with experimental observations of Janus particles.
This is a roughly weekly series of didactical blackboard talks focussing on some theoretical aspect of Condensed Matter, Biological, and Statistical Physics..
