Synchro-nematic and -antinematic ordering of spheroidal circle swimmers
Anson G. Thambi, Alexander N. Dodge, William E. Uspal
Chirality gives a microswimmer something a straight-line swimmer lacks: a phase. This variable both modulates, and is affected by, the hydrodynamic interactions between microswimme…

Clustering and emergent hyperuniformity by breaking microswimmer shape and actuation symmetries
Anson G. Thambi, William E. Uspal
Hydrodynamic interactions driven by particle activity are ubiquitous in active colloidal systems. Although these interactions are strongly influenced by the interfacial actuation m…

Hydrodynamic Stokes flow induced by a chemically active patch imprinted on a planar wall
Mihail N. Popescu, Bogdan Adrian Nicola, William E. Uspal +2
Patches of catalyst imprinted on supporting walls induce motion of the fluid around them once they are supplied with the chemical species (``fuel'') that are converted by the catal…
