Theory And Experiment

In this paper, using the first-principles calculations, we study the crystal structure effect on the superconductivity in CaAlSi . It is proposed that an AF-like superstructure model for Al (or Si ) atoms arranged along the c direction may mediate the inconsistency of the electron-phonon coupling estimated from theory and experiment, and explain the anomalous superconductivity in CaAlSi .
