论文摘要
我们开发了一个统一的框架，通过利用格林功能的对称分类来理解费米介导的相互作用的迹象。特别是，我们建立了有关手性对称系统中费米介导相互作用的迹象的定理。在多个示例中证明了该定理的强度，重点是材料中电子介导的相互作用。
We develop a unified framework for understanding the sign of fermion-mediated interactions by exploiting the symmetry classification of Green's functions. In particular, we establish a theorem regarding the sign of fermion-mediated interactions in systems with chiral symmetry. The strength of the theorem is demonstrated within multiple examples with an emphasis on electron-mediated interactions in materials.
