# Nambu-Goldstone Modes for Superconducting Lattice Fermions

@inproceedings{Koma2022NambuGoldstoneMF, title={Nambu-Goldstone Modes for Superconducting Lattice Fermions}, author={Tohru Koma}, year={2022} }

: We present a lattice model for superconducting fermions whose nearest-neighbour two-body interactions are a Bardeen-Cooper-Schrieﬀer-type pairing on the hypercubic lattice Z d with the dimension d ≥ 3. Although these eﬀective interactions between two electrons are believed to be caused by electron-phonon interactions, we assume that the interactions between two electrons are of short range without phonons. For the model, we prove the existence of the long-range order of the superconductivity…

The many-body ground state of a very general class of electron-phonon Hamiltonians is proven to contain a spin singlet and both the spin-singlet and uniqueness theorems apply to the Holstein and attractive Hubbard models as special cases.
