Experimental phase dynamics. (a),(b) Phase difference relative to the first rotor, ϕ_i − ϕ₀, at h = 11.7 μm. (c) Wobbles are characterized by their magnitude W (radians) and timescale τ/〈T〉 (normalized by rotor period), shown as a function of h in panels (d) and (e). (f) Probability that a propagating wobble ends at rotor i, resulting in a slip.
