Dielectric Screening
The dielectric matrix of Strontium iodide (SrI2) is computed in WEST by iterative diagonalization, see Fig. 2 of Ref. [04].
The eigenvalues of the symmetrized irreducible polarizability for Strontium iodide (SrI2) are reported in Fig. 1.
Results were obtained using the program wstat.x
of the WEST package.
Fig. 1 - Eigenvalues of the symmetrized irreducible polarizability for Strontium iodide (SrI2). The calculations were performed with two exchange-correlation functionals: PBE and PBE0; pseudopotentials: Scalar Relativistic (SR), Fully Relativistic (FR).
Spectral Function
The G0W0 spectral function of Strontium iodide (SrI2) is computed in WEST with full frequency integration.
Results were obtained using the program wfreq.x
of the WEST package.
