Tunnelling control by a magnetic field in the system of two
concentric quantum rings
A. A. Bryzgalov, F. I. Karmanov Obninsk Institute for Nuclear Power Engineering
Abstract:
The operation of a quantum device consisting of two concentric rings and
controlling by an alternating magnetic field is demonstrated using a double-well
potential model. The electron tunnelling between the rings is modelled by the
method of splitting into physical processes. This method uses the previously
calculated eigenvalues and eigenfunctions for various values of the magnetic
field strength. The number of basis functions for the splitting method
is evaluated for some different modelling cases.
Keywords:
eigenvalue problem; asymmetric double-well potential; nonstationary Schroedinger equation; alternating magnetic field; electron tunnelling; concentric quantum rings; control of the wave packet position.
