Multiband superconductivity in $\mathrm{Bi}{\mathrm{S}}_2$-based layered compounds

M. A. Griffith, T. O. Puel, M. A. Continentino +1

A mean-field treatment is presented of a square lattice two-orbital-model for $\mathrm{Bi}{\mathrm{S}}_2$ taking into account intra- and inter-orbital superconductivity. A rich phase diagram inv…
