Abstract

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.

奇偶多极波动介导的场致超导电性

场致超导长期以来一直是凝聚态物理学中的一个反直觉现象和关键挑战。在本文中，我们介绍了一种实现场致超导的机制，其中亚晶格自由度和库仑相互作用紧密地纠缠在一起。我们的多极分辨分析阐明，解除波动变性会产生非常规的库珀配对通道，从而实现场致超导。这项研究极大地增强了对具有亚晶格自由度的强相关电子系统潜在潜力的探索。
