Figure 2

(a) Real part of electron self-energy (Σ′) at different delay times (t= −1, 1 and 10 ps) for pump fluences 8 and 24 μJ cm−2 measured at 17 K (below Tc). Σ′ measured at equilibrium temperature 100 K (above Tc) is plotted in the lowest panel for comparison. (b) The corresponding MDC width as a function of energies. The black arrows mark the energy ~ħω0 where non-equilibrium and equilibrium MDC width separate with each other. Inset in the lowest panel shows non-equilibrium MDC width at 17 and 108 K (ref. 32). (c) Σ′ and MDC width, similar to that shown in a,b but measured in the normal state with pump fluence 13 μJ cm−2, at an equilibrium temperature of 100 K.
