Spectra of distorted quantum ring in external fields

SILOTIA, POONAM ; Giri, Rajesh ; Prasad, Vinod


The spectra and response of a single electron on a distorted quantum ring have been studied in detail. The distortion in the ring has been taken care by a geometrical factor. We take few different cases of distortion. Role of strength of the distortion along with the external static and laser field on spectrum has been studied.
