Band structure and electron-phonon coupling in H${}_3$S:a tight-binding model

Luciano Ortenzi, Emmanuele Cappelluti, Luciano Pietronero

We present a robust tight-binding description, based on the Slater-Koster formalism, of the band structure of H${}_3$S in the {\em Im}$\bar{3}${\em m} structure, stable in the range…
