Growing correlation length on cooling below the onset of caging in a simulated glass-forming liquid
Growing correlation length on cooling below the onset of caging in a simulated glass-forming liquid
We present a calculation of a fourth-order, time-dependent density correlation function that measures higher-order spatiotemporal correlations of the density of a liquid. From molecular dynamics simulations of a glass-forming Lennard-Jones liquid, we find that the characteristic length scale of this function has a maximum as a function of time which …
