Suppression of superconductivity in high-$T_c$ cuprates due to nonmagnetic impurities: Implications for the order parameter symmetry

M. Bayindir, Z. Gedik

We studied the effects of nonmagnetic impurities on high-temperature superconductors by solving the Bogoliubov-de Gennes equations on a two-dimensional lattice via exact diagonaliz…
