Query: Magneto-transport in mesoscopic rings and cylinders: Effects of
  electron-electron interaction and spin-orbit coupling   We undertake an in-depth analysis of the magneto-transport properties in
mesoscopic single-channel rings and multi-channel cylinders within a
tight-binding formalism. The main focus of this review is to illustrate how the
long standing anomalies between the calculated and measured current amplitudes
carried by a small conducting ring upon the application of a magnetic flux
$\phi$ can be removed. We discuss two different cases. First, we examine the
combined effect of second-neighbor hopping integral and Hubbard correlation on
the enhancement of persistent current in presence of disorder. A significant
change in current amplitude is observed compared to the traditional
nearest-neighbor hopping model and the current amplitude becomes quite
comparable to experimental realizations. In the other case we verify that in
presence of spin-orbit interaction a considerable enhancement of persistent
current amplitude takes place, and the current amplitude in a disordered ring
becomes almost comparable to that of an ordered one. In addition to these, we
also present the detailed band structures and some other related issues to get
a complete picture of the phenomena at the microscopic level.
