摘要: Formation of bound pairs in two dimensional t–J models is investigated. Previous studies have examined the square and rectangular lattices, here we extend such work to include triangular lattice. In particular, calculate threshold exchange coupling needed for pairing, corresponding binding energy an isotropic Finally, track how a frustrated environment affects pairing considered anisotropic model with couplings J1 J2 which smoothly interpolates between lattices.
