Geometrical frustration leads to novel quantum phenomena such as the spin-liquid phase in triangular and kagome lattices. Intraband and interband Fermi surface (FS) nesting can drive unique superconducting (SC) ground states with $d$-wave and ${s}^{\ifmmode\pm\else\textpm\fi{}}$-pairing symmetries, respectively, according to the criterion that the SC gap changes sign across the nesting …
