Superconductivity and lattice instability in face-centered cubic lanthanum under high pressure

The lattice dynamics and superconductivity of face-centered cubic (fcc) La under pressure are extensively studied using the linear-response methods within the framework of density-functional theory. A pressure-induced softening transverse acoustic (TA) phonon mode at the L point of the Brillouin zon...
