“…It has been found that the calculated optical properties for AsNMg 3 and SbNMg 3 [19], ZnY (Y = S, Se and Te) [20], SrX(X = S, Se and Te) [21] and LaFe 4 P 12 [22] are in excellent agreement with the experimental findings, and we have therefore used the same theory to predict the optical properties of Fe 2 TiSn. To our knowledge, there are no experimental data concerning the imaginary parts of the dielectric function for the Fe 2 TiSn.…”

Full-potential linearized augmented plane wave and local orbital method calculations were performed for Fe2TiSn in order to investigate the optical properties and to show the origin of the different optical transitions. It is found that the band gap is indirect for Fe2TiSn. Then our calculated reflectivity spectra are in good agreement with the experimental results. On the other hand, the contributions of various transition peaks are analysed from the imaginary part of the dielectric function. Furthermore, the different optical properties have been investigated.

We report the pressure dependence of critical temperature on superconductivity (T c) of a filled skutterudite YRu 4 P 12 by measuring magnetization and resistivity up to 2.4 GPa and 8.0 GPa, respectively. We found that T c is almost independent to pressure up to 2.4 GPa and it shows a gradual decrease in the pressure range of 4.0 to 8.0 GPa. The pressure derivative of T c (dT c /dP) is-0.3 K/GPa in maximum and it is quite different from the (dT c /dP) ∼ 1.0 K/GPa of YFe 4 P 12. This study experimentally clarified the negative pressure dependence of YRu 4 P 12 , which was predicted based on a full potential linearized augmented plane wave calculation. In addition, we report the magnetic field dependence of T c of YRu 4 P 12 shows µ 0 H c2 (0) ∼ 3.2 T which is lower than the Pauli limiting field of ∼ 14 T and suggests that YRu 4 P 12 is a BSC-type superconductor.

“…The full‐potential linear augmented plane method (FP‐LAPW‐DFT) implemented in the WIEN2K code3 is one of the most used in the literature to simulate the ELF spectra4. In most cases, this approach reproduces fairly well the experimental spectra but the nature of the interband transitions is rarely investigated5, 6. Another approach to calculate the ELF function is based on the “sum over states” (SOS) calculation of static and dynamic polarizability using the one‐electron eigenfunctions and eigenvalues provided by the periodic code CRYSTAL097.…”

We perform ab initio calculations of the optical absorption and electron energy-loss spectra of (m, 0) single-walled carbon nanotubes (with m = 3n for m ¼ 7-25) in the framework of a ''sum over states'' (SOS) treatment of the Kohn-Sham (KS) single-particle orbitals and energies (CRYSTAL program). This approach tested on hexagonal boron nitride enables to fully assign the interband transitions in the imaginary part of the dielectric constant, in terms of atomic orbitals. As these calculations could not take into account the local field effects (depolarization effects), which take place for perpendicular polarizations in 2D and 1D periodic systems, we apply a simple method based on the Clausius-Mossotti formula, relating the SOS and coupled-perturbed KS polarizability values. This approach reproduces the main features of the spectra of boron nitride (001) surface and carbon nanotubes.
