Quasi-point versus point nodes in , the case of a flat tight binding sheet

Abstract
We perform a numerical study of the unitary regime as a function of disorder concentration in the imaginary part of the elastic scattering cross-section for the compound in the flat band non-disperse limit. By using a self-consistent tight-binding (TB) method, we find a couple of families of Wigner probabilistic functions that help to explain macroscopically the distribution between Fermion dressed quasiparticles and Cooper pairs, and also the position of nodes in the order parameter for . Therefore, we are able to show that a TB model for the sheet numerically shows 4 point nodes in a flat sheet limit or 4 quasi-point nodes for strong dispersion sheet limit in the reduced phase scattering space (RPS).
