Electron–phonon coupling and superconductivity in an alkaline earth hydride CaH6 at high pressures
Recently, an alkaline earth hydride CaH _6 having a sodalitelike clathrate structure has been experimentally synthesized at megabar pressures with a maximum T _c of 215 K, comparable to that of a rare earth hydride LaH _10 . Here, based on first-principles calculations, we find that CaH _6 exhibits...
