Electronic States in a Cylindrical Quantum Dot under the Influence of Gaussian and Bessel Laser Beams

Abstract

The electronic states in a cylindrical quantum dot with a modified Pöschl–Teller confinement potential under the influence of high-frequency laser radiation are considered. Two types of laser radiation are considered: Gaussian and Bessel. Under the influence of high-frequency laser radiation, the confinement potential of the quantum dot is converted to a new, effective confinement potential. For example, in the case of a Bessel beam, instead of a Pöschl–Teller potential well, a double potential well is obtained in the axial direction. This leads to an interesting behavior of the energy states of the electron. In particular, the abovementioned leads to the formation of anti-crossing of the states, as well as to the merging of the neighboring pairs of energy levels.
