Derivation of d-wave symmetry in real-space superconductors
arXiv:2502.04647
Abstract
A simple derivation of -wave order parameter within the real-space pairing and Bose-Einstein condensation mechanism of superconductivity is given. The two key ingredients are a short-range attraction between carriers and hole-like hopping between equal-energy pair configurations.
