Origin of strong coupling in lithium under pressure

Original language description

In an attempt to provide a clearer understanding of the impressive increase in Tc under pressure in elemental Li, linear response calculation of the phonon dispersion curves, electron?phonon matrix elements, phonon linewidths and mode ??s have been carried out for the volume corresponding to 20 GPa pressure. The current results show that the high value of Tc gets strong contributions from elsewhere in the zone, particularly from the longitudinal mode along (1 0 0).
