Driven rotational dynamics. a Steady-state angular velocity for the particles of a N = 30 chain, in which particle 1 is externally driven at an angular velocity 10 GHz. All of the particles have the same diameter D and are uniformly distributed with a center-to-center distance d, as shown in the inset. b Same as a, but, in this case, two particles, which are indicated with small arrows (see legend), are externally driven at angular velocities 10 and −10 GHz, respectively
