Figure 2: trPES for (V1−xCrx)2O3 for the PI and PM phases at a fluence of 1.8 mJ cm−2.

From: Ultrafast evolution and transient phases of a prototype out-of-equilibrium Mott–Hubbard material

Figure 2

(a) Time evolution of the intensity difference at −0.1 eV, the curve is fitted with a double exponential. (b) PES intensity difference for Δt=50 fs, 400 fs and 2 ps are shown for the PI phase as well as the equilibrium temperature difference from Fig. 1. The 50 and 400 fs differences show that the spectral weight is transferred inside the Mott gap, differently from a purely thermal effect. This non-thermal distribution relaxes within 2 ps. (c) Orbital character of the DOS near EF extracted from ref. 22. (df) Same as (ac) but for the PM phase. The time evolution is fitted with a double exponential for the energy above EF.
