This study investigated the gap-to-Tc ratios and superfluid density of anisotropic s-wave superconductors under external pressure using the BCS theory and the semiclassical approach. The gap-to-Tc ratio and superfluid density were developed based on our pressure parameter assumptions to describe the anisotropic s-wave in CaAlSi and the isotropic s-wave in H3S and LaH10 superconductors. The gap-to-Tc ratios were calculated, and the results showed that H3S, LaH10, and CaAlSi were 3.72, 3.68, and 3.53, respectively. The differences of superfluid densities between the baseline and variations in pressure parameters reach their maximum at T/Tc ≈ 0.7, approximately. Finally, we can conclude that the BCS theory and semiclassical approach can account for describe the behaviour of H3S, LaH10 and CaAlSi superconductors under high pressure. © 2023 |
