Field-induced superconductivity mediated by odd-parity multipole fluctuation
Field-induced superconductivity has long presented a counterintuitive phenomenon and a pivotal challenge in condensed matter physics. In this paper, we introduce a mechanism for achieving field-induced superconductivity wherein the sublattice degree of freedom and the Coulomb interaction are tightly entwined. Our multipole-resolved analysis elucidates that lifting the fluctuation degeneracy results in an unconventional Cooper pairing channel, thereby realizing field-induced superconductivity. This research substantively augments the exploration of the latent potential of strongly correlated electron systems with sublattice degrees of freedom.
