  In this study, we propose a recursive approach to study the transport
properties of atomic wires.
  It is based upon a real-space block-recursion technique with Landauer's
formula being used to express the conductance as a scattering problem. To
illustrate the method, we have applied it on a model system described by a
single band tight-binding Hamiltonian. Results of our calculation therefore may
be compared with the reported results on Na-atom wire. Upon tuning the
tight-binding parameters, we can distinctly identify the controlling parameters
responsible to decide the width as well as the phase of odd-even oscillations
in the conductance.
