In the present work we investigate the coherent electron transport in a symmetrically designed ballistic ring uniformly covered by a top metal gate. We ΓΏnd that as the Fermi energy is varied, the phase of Aharonov-Bohm (AB) oscillations near zero magnetic ΓΏeld switches between 0 and . It seems unlik
