The Quantization of Mesoscopic LC-circuits. Basic Ideas and Applications

摘要

In this paper one deals with the quantization of mesoscopic LC-circuits under the influence of an external time dependent voltage. The canonically conjugated variables, such as given by the electric charge and the magnetic flux get established by resorting to the hamiltonian equations of motion. This time the discretization of the electric charge is accounted for by working in combination with both right-hand and left-hand discrete derivatives. This results in the onset of related magnetic flux operators. Besides the discrete Schr?dinger equation with nearest-neighbor hoppings, a nontrivial next nearest neighbor generalization has also been established. Handling the time dependent voltage within the nearest neighbor description opens the way to the derivation of dynamic localization effects in terms of the approach discussed before by Dunlap and Kenkre, L-ring configurations included.
