Abstract
Elastic scattering in a quantum wire has several novel features not seen in one dimension (1D), 2D, or 3D. In this work we consider a single channel quantum wire as its application is inevitable in making devices based on quantum interference effects. We consider a point defect or a single delta function impurity in such a wire and show how some of these novel features affect Friedel-sum-rule (FSR) in a way, that is quite unlike in 1D, 2D, and 3D.
