# $\pi$ Flux Phase and Superconductivity for Lattice Fermions Coupled to Classical Gauge Fields

@inproceedings{Koma2022piFP, title={\$\pi\$ Flux Phase and Superconductivity for Lattice Fermions Coupled to Classical Gauge Fields}, author={Tohru Koma}, year={2022} }

: We study superconducting lattice fermions coupled to classical gauge ﬁelds. Namely, without the gauge ﬁelds, the lattice fermions show superconducting long-range order. In the previous paper, the existence of the long-range order was proved by the present author. This paper is the continuing part of the previous one. More precisely, the interactions between fermions were assumed to be a Bardeen-Cooper-Schrieﬀer-type pairing which is a nearest-neighbour two-body interaction on the hypercubic…
