Angular velocities in the self-spinning glass phase. (a) Snapshots of the particle orientations \({\hat{{\bf{u}}}}_{i}\) (blue arrows), instantaneous velocities v _i (red arrows), and normalized angular velocities \({\hat{{\boldsymbol{\omega }}}}_{i}\) (purple arrows) for an arbitrary glassy configuration of N = 800 particles with aspect ratio a = 2 at packing fraction ϕ = 0.5. (b) Corresponding time correlation functions C _s (t) and C(t), probing the self- and collective parts of the angular-velocity autocorrelation, respectively. The solid purple line indicates the analytical prediction of C _s (t) for a rotation period of T = 14410τ.
