Figure 4: Evolution of amplitude and QP relaxation time.

(a) Quasiparticle relaxation time (black squares, left axis) and the amplitude (red open circles, right axis) of the pseudogap component (data shown in b) as a function of tD−P. Quasiparticle relaxation time remains constant for all values of tD−P. The error bars represent s.d. obtained from the fit. (b) Pseudogap component for different values of tD−P (, T=120 K).
