Quantum scattering in the strip: from ballistic to localized regimes
Quantum scattering is studied in a system consisting of randomly distributed
point scatterers in the strip. The model is continuous yet exactly solvable.
Varying the number of scatterers (the sample length) we investigate a
transition between the ballistic and the localized regimes. By considering the
cylinder geometry and introducing the magnetic flux we are able to study time
reversal symmetry breaking in the system. Both macroscopic (conductance) and
microscopic (eigenphases distribution, statistics of S-matrix elements)
characteristics of the system are examined.Comment: 17 pages and 10 figures (15 eps files); accepted for publication in
