Influence of Rashba and Dresselhaus Spin-Orbit Interactions of Equal Strengths on Electron States in a Circular Quantum Ring in the Presence of a Magnetic Field.
V. V. Kudryashov and A. V. Baran

Solutions of the Schrödinger equation are obtained for an electron in a two-dimensional circular semiconductor quantum ring in the presence of both external uniform constant magnetic field and the Rashba and Dresselhaus spin-orbit interactions of equal strengths. Confinement is simulated by a realistic potential well of a finite depth. The dependence of the energy levels on a magnetic field strength, strength of spin-orbit interaction and a relative ring width is presented.

Key words: circular quantum ring, Rashba and Dresselhaus spin-orbit interactions, magnetic field
