"integrates Su-Schrieffer-Heeger electron-phonon coupling with Hubbard electronic interactions, showing that interplay between electron-phonon coupling and Hubbard interaction is key... intricate competition among s-wave superconductivity, d-wave superconductivity, and stripe charge-density order. Crucially, the study identified that Su-Schrieffer-Heeger-induced effective antiferromagnetic exchange interactions are pivotal for stabilizing d-wave superconductivity"
