Fig. 5: Theoretical calculations.
a A schematic of band diagram considered for computing inter band transitions when the conduction electron is coupled to glassy background from randomly oriented polar nano regions. b (Upper panel) The glass correlation function Cgl(t) vs. t for three temperatures for τs(T) = 1, b = 0.5. (Lower panel) Plot of τα(T) ~ T−2.8 vs. T (left y axis, in units of τs) and B(T) (right y axis) vs. T (A = 1 − B) for three temperatures. c (upper panel) The density-density correlation function of conduction electron Cel(t) vs. t for three temperatures for flat (W = 0) conduction band. (lower panel) Cel(t) vs. t for three temperatures for semicircular conduction band with W = 0.01. Source data are provided as a Source data file.
