Characterization of active matter in dense suspensions with heterodyne laser Doppler velocimetry
Johannes Sachs, S. Nikhilesh Kottapalli, Peer Fischer +2
We present a novel approach for characterizing the properties and performance of active matter in dilute suspension as well as in crowded environments. We use Super-Heterodyne Lase…

The role of symmetry in driven propulsion at low Reynolds number
Johannes Sachs, Konstantin I. Morozov, Oded Kenneth +4
We theoretically and experimentally investigate low-Reynolds-number propulsion of geometrically achiral planar objects that possess a dipole moment and that are driven by a rotatin…
