Modulation of pairing symmetry with bond disorder in unconventional superconductors

Yao-Tai Kang, Wei-Feng Tsai, Dao-Xin Yao

We study a two-orbital $t$-$J_1$-$J_2$ model, originally developed to describe iron-based superconductors at low energies, in the presence of bond disorder (via next-nearest-neighb…
