摘要
We study a two-electron system of a quantum ring under the influence of a perpendicular homogeneous magnetic field. Calculations are made by using the method of numeri cal diagonalization of Hamiltonian matrix within the effective-mass approximation. A ground-state behavior (spin singlet-triplet transitions) as a function of the strength of a magnetic field is investigated. We find that the ring radius R(0) and the ring width W are important for the singlet-triplet transition of the ground-state
