Hole Burning Spectroscopy of Polymer Glasses

I am currently working of Mechanical spectral hole burning of polymer glasses (MSHB). In this work we test the modified linear response of glassy materials after the application of a large (non-linear) sinusoidal deformation. We intend to explore the dynamic heterogeneities in the material and possible causes for it. In glasses, we test the role of β-transition (secondary transition) on the hole burning event. Also, these MSHB results can be used to test the current existing non-linear viscoelastic models such as that of BKZ.
