Query: Pattern Formation in Chemically Interacting Active Rotors with
  Self-Propulsion   We demonstrate that active rotations in chemically signalling particles, such
as autochemotactic {\it E. coli} close to walls, create a route for pattern
formation based on a nonlinear yet deterministic instability mechanism. For
slow rotations, we find a transient persistence of the uniform state, followed
by a sudden formation of clusters contingent on locking of the average
propulsion direction by chemotaxis. These clusters coarsen, which results in
phase separation into a dense and a dilute region. Faster rotations arrest
phase separation leading to a global travelling wave of rotors with
synchronized roto-translational motion. Our results elucidate the physics
resulting from the competition of two generic paradigms in active matter,
chemotaxis and active rotations, and show that the latter provides a tool to
design programmable self-assembly of active matter, for example to control
coarsening.
