Fig. 2: Pressure dependence of hybridization function and local spectra density.
From: Pressure-induced concomitant topological and metal-insulator quantum phase transitions in Ce3Pd3Bi4
a–c The real (solid lines) and imaginary (dashed lines) part of the hybridization function. d–f the integrated spectra density at 29, 58, and 116 K, for 98%, 96%, 94%, 92%, and 90% compressed cell volume, respectively. The magnitude of the energy gap is plotted as the function of cell volume shown in the inset of (d, e). The gap size is evaluated from the half-height of the maximal intensity at the gap edge below EF to the minimal intensity value inside the gap as schematically illustrated in the inset of (f). The black dashed line in the inset of (f) marks the valence bands edge Ev.
