Our work on how boundary conditions affect the diffusive transport of active particals in a lattice of pillars we published today in Phys Rev E

Microswimmers obey peculiar rules for scattering off surfaces and obstacles. For example, swimming bacteria slide along the surface of a circular obstacle before leaving its surface, in contrast with the specular reflection of a classical Lorentz gas particle. These different scattering rules translate into marked differences in the predicted diffusive transport in a dense lattice of obstacles, as we showed in our paper by numerical simulation and analytically.
