Fig. 1: Temperature and scattering vector dependence of time-domain interferograms.
From: Experimental evidence of mosaic structure in strongly supercooled molecular liquids
Time-domain interferometry data as a function of time (squares with ±1 SD errorbars) at different temperatures and at a fixed exchanged wave-vector (q = 15 nm−1, roughly corresponding to the inter-molecular distance) a and at the same temperature T = 122.5 K in the supercooled liquid state and at different q values b. The raw data have been averaged over a time range ±0.7 and ±0.9 ns, respectively, depending on the collected statistics, in order to improve the figure readability. The black solid lines are the model curves obtained from the fitting procedure. The blue solid lines are the calculated contrast functions, \({\phi }^{\prime}\), along with the 68% confidence interval (gray area). \({\phi }^{\prime}\) is proportional to the density correlation function.
