Extended Data Fig. 8: Partial-wave analysis with the screened scattering potential.
From: Pseudogap in a crystalline insulator doped by disordered metals
a, Phase shift δl of the partial waves calculated by the screened scattering potential for the liquid phase of Cs ions, which clearly shows d-wave resonance9. The dotted line is a fit with that calculated by the spherical step potential at V0 = 12.96 eV and rs = 2.1 Å. b, Phase shift δl of partial waves calculated by the screened scattering potential of Na, K, Rb and Cs ions30. K, Rb and Cs ions favour d-wave resonance, whereas the Na ions favour p-wave resonance, which is exactly as observed in our experiments. Our results reproduce other details as well. (1) δl crosses π/2 clearly for K, Rb and Cs ions, whereas that for Na ions is relatively incomplete. (2) The δl values of K and Rb ions are nearly the same. (3) The abruptness of δl, which is related to the magnitude of the pseudogap, increases in the order of Na → K/Rb → Cs.
