A $B_{1g}$ phonon unlocks $d$-wave superconductivity in the repulsive Hubbard model

Wen O. Wang, Tianshu Li, Xiaoyue Ma +9

Using numerically exact finite-temperature quantum Monte Carlo, we demonstrate that a $B_{1g}$ phonon coupled to the doped $t$-$t^{\prime }$ repulsive Hubbard model produces genuine $d$-wav…
