 abstract = {Temporal relaxation of density fluctuations in supercooled liquids near
the glass transition occurs in multiple steps. Using molecular dynamics
simulations for three model glass-forming liquids, we show that the
short-time beta relaxation is cooperative in nature. Using finite-size
scaling analysis, we extract a growing length scale associated with beta
relaxation from the observed dependence of the beta relaxation time on
the system size. We find, in qualitative agreement with the prediction
of the inhomogeneous mode coupling theory, that the temperature
dependence of this length scale is the same as that of the length scale
that describes the spatial heterogeneity of local dynamics in the
long-time alpha-relaxation regime.},
