Aharonov-Bohm Effect in the Spectrum of Eigenmodes in Semiconductor Nanotubes with Dielectric Filling in DC Magnetic Field

The dispersion properties of electromagnetic eigenmodes in a semiconductor nanotube filled by a nonmagnetic dielectric and placed in a coaxial DC magnetic field have been studied theoretically. A new quantum electrodynamical phenomenon has been predicted. An increase of the two-dimensional electron density in the nanotube is shown to lead to the appearance of more and more new branches in the eigenmodes spectrum. It has been demonstrated that the number of branches monotonously increases when increasing the two-dimensional electron density and experiences the Aharonov-Bohm oscillations with growth of the number of magnetic flux quanta through the nanotube.
