Description
Active matter systems are composed of individual units driven away from equilibrium. Their examples include suspensions of microorganisms and autophoretic particles. I will present a continuum theory of phase separation in suspensions of active particles. I will show that the steady-states in this theory are governed by the effective mechanical (causing flow) and diffusive (causing Ostwald ripening) tensions. In the second part of the talk, I would present a microscopic theory to study the collective dynamics of active particles with phoretic and hydrodynamic interactions. Finally, I would describe my work on the Bayesian inference of the Ornstein Uhlenbeck process.
