First-principles study of the pressure and crystal-structure dependences of the superconducting transition temperature in compressed sulfur hydrides

Ryosuke Akashi, Mitsuaki Kawamura, Shinji Tsuneyuki +2

We calculate superconducting transition temperatures ($T_{\mathrm{c}}$) in sulfur hydrides H${}_2$S and H${}_3$S from first principles using the density functional theory for supercondu…
