    • However, there is a natural time at which the spatial correlation of particle mobilities is the most pronounced. See C. Donati, S.C. Glotzer, and P.H. Poole, Phys. Rev. Lett. 82, 5064 (1999)

    • We have observed that a small fraction of mobile particles have a tendency to return to their initial positions at times longer than (Formula presented). These particles may be responsible for this small memory effect, but further analysis needs to be done
