Abstract
AbstractThe behavior of Ne interacting electrons confined in a mesoscopic “quantum” cylinder, QC, threaded by an Aharonov–Bohm (AB) flux ϕ is carefully analyzed by using a Hartree–Fock approximation. The ground state energies of the QC as a function of the magnetic field, B, and the electron–electron repulsion strength, U, are obtained. A phase diagram is presented indicating a rich variety of ground states and the spin and orbital magnetization responses to the magnetic field's variations are discussed. The behavior of persistent current is investigated and a significant change in current amplitude is observed when the strength of the electron–electron repulsion increases.
