Hole-burning experiments within glassy models with infinite range interactions
We reproduce the results of nonresonant spectral hole-burning experiments with glassy models with infinite-range interactions that generalize the mode-coupling approach to nonequilibrium situations. We show that an ac field modifies the integrated linear response and the correlation in a way that depends on the amplitude and frequency of the pumping field. We study the effect of the waiting and recovery times and the number of oscillations applied. This calculation will help discriminate which results can and which cannot be attributed to spatial heterogeneities in real systems.
