Active Particles on Curved Surfaces
read the original abstract
Recent studies have highlighted the sensitivity of active matter to boundaries and their geometries. Here we develop a general theory for the dynamics and statistics of active particles on curved surfaces and illustrate it on two examples. We first show that active particles moving on a surface with no ability to probe its curvature only exhibit steady-state inhomogeneities in the presence of orientational order. We then consider a strongly confined 3D ideal active gas and compute its steady-state density distribution in a box of arbitrary convex shape.

Frustrated Fields: Statistical Field Theory for Frustrated Brownian Particles on 2D Manifolds
Frustrated Brownian particles on 2D manifolds form a precessing ring whose orientation dynamics are governed by the RP^2 nonlinear sigma model, with the rotational diffusion coefficient and ring profile fixed by simul...

Origin of Persistent Boundary Motion in Confined Active Matter
Active Brownian particles in circular confinement accumulate at the boundary with positional power-law decay linked to curvature-induced bistable tangential orientations and stochastic switching between boundary-local...
