Jz. Zhu et al., THEORETICAL INVESTIGATIONS OF ELECTRONIC TRANSPORT IN A QUASI-ONE-DIMENSIONAL WIRE WITH A ZERO-RANGE SCATTERER, Communications in Theoretical Physics, 22(4), 1994, pp. 483-486
By assuming a special form of scatterer, we obtain an exact solution o
f the Dyson's equation for a quasi-one-dimensional wire, and discuss s
ome insight about the electron scattering in a confined geometry.
