Variational Quantum Monte Carlo investigations of the superconducting pairing in La${}_3$Ni${}_2$O${}_7$

Yi-Qun Liu, Da Wang, Qiang-Hua Wang

We investigate the pairing symmetry in the novel superconductor La${}_3$Ni${}_2$O${}_7$ under pressure by the non-perturbative variational quantum Monte Carlo. Within the bilayer Hubbard…
