Topological superconductivity in Sn/Si (111) driven by nonlocal Coulomb interactions

M Biderang, MH Zare, J Sirker - Physical Review B, 2022 - APS
Superconductivity was recently observed in boron-doped (3× 3) Sn/Si (111). The material
can be described by an extended Hubbard model on a triangular lattice. Here, we use the …

Nematicity-enhanced superconductivity in systems with a non-Fermi liquid behavior
