Minimum Dissipation Theorem for Microswimmers
Babak Nasouri, Andrej Vilfan, Ramin Golestanian
We derive a theorem for the lower bound on the energy dissipation rate by a rigid surface-driven active microswimmer of arbitrary shape in a fluid at low Reynolds number. We show t…

Exact axisymmetric interaction of phoretically active Janus particles
Babak Nasouri, Ramin Golestanian
We study the axisymmetric interaction of two chemically active Janus particles. By relying on the linearity of the field equations and symmetry arguments, we derive a generic solut…

Exact phoretic interaction of two chemically-active particles
Babak Nasouri, Ramin Golestanian
We study the nonequilibrium interaction of two isotropic chemically-active particles taking into account the exact near-field chemical interactions as well as hydrodynamic interact…
