Avoided crossings in mesoscopic systems:Electron propagation on a nonuniform magnetic cylinder.
Original language description
We consider an electron constrained to move on a surface with revolution symmetry in the presence of a constant magnetic field B parallel to the surface axis. Depending on B and the surface geometry the transverse part of the spectrum typically exhibitsmany crossings which change to avoided crossings if a weak symmetry breaking interaction is introduced. We study the effect of such perturbations on thequantum propagation. This problem admits a natural reformulation to which tools from molecular dynamics can be applied. In turn, this leads to the study of a perturbation theory for the time dependent Born-Oppenheimer approximation.
