| Using an attractive Hubbard model, we examine spatial variations of superconducting order parameter and local charge on a two-dimensional lattice. For various band filling, we show the effect of destruction of the order parameter around a non-magnetic impurity. In case of a half-filled system such destruction is accompanied by appearance of characteristic charge variations around the impurity with an isotropic distribution. |
