Symmetry background of the fractional Aharonov-Bohm oscillation and an oscillation in dipole-transitions of narrow quantum rings with a few-electrons

C. G. Bao, G. M. Huang, Y. M. Liu

The low-lying spectrum of a 3-electron narrow ring has been analyzed analytically. A phase-diagram for the ground state band against the magnetic field and the radius of the ring i…
