Transition Temperature of Superconductivity in Sodium Tungsten Bronze -Theoretical Study Based on First-principles Calculations-

Kazuhiro Sano, Yoshihiro Nitta, Yoshiaki Ōno

Using first-principles calculations, we examine the transition temperature $T_{\mathrm{c}}$ of superconductivity in sodium tungsten bronze ( Na${}_x$WO${}_3$, where $x$ is equal to or less…
