(a) Mean squared displacement (MSD) versus strain of a sheared colloidal glass for different strain rates. The inset shows the distribution function of particle displacement for <math>\gamma = 0.08</math> (non-Gaussian, red squares) and <math>\gamma = 1</math> (Gaussian, blue circles).

(b) MSD versus strain, calculated over time intervals that have been chosen after the onset of diffusive behavior. The similarity of this graph with (a) indicates that there is no critical amount of shear strain that is sufficient to describe an absolute phase transition in this system.

(c) Normalized non-Gaussian parameter <math>\alpha_2</math> as a function of strain.

(d) Normalized non-Gaussian parameter <math>\alpha_2</math> as a function of strain, computed over time intervals beginning after the onset of diffusive behavior.
