Effective pairing interaction in the two-dimensional Hubbard model within a spin rotationally invariant approach

V. A. Apinyan, T. K. Kopec

We implement the rotationally-invariant formulation of the two-dimensional Hubbard model, with nearest-neighbors hopping , which allows for the analytical study of the system in…
