Active Particles with Soft and Curved Walls: Equation of State, Ratchets, and Instabilities
We study, from first principles, the pressure exerted by an active fluid of spherical particles on general boundaries in two dimensions. We show that, despite the nonuniform pressure along curved walls, an equation of state is recovered upon a proper spatial averaging. This holds even in the presenc...
