Spin–orbit coupling, minimal model and potential Cooper-pairing from repulsion in BiS2-superconductors

We develop the realistic minimal electronic model for recently discovered BiS _2 superconductors including the spin–orbit (SO) coupling based on the first-principles band structure calculations. Due to strong SO coupling, characteristic for the Bi-based systems, the tight-binding low-energy model ne...
