英文摘要 | The properties of the ground state of a closed dot-ring system with a magnetic flux in the Kondo regime are studied theoretically by means of a one-impurity Anderson Hamiltonian. The Hamiltonian is solved by means of the slave-boson mean-field theory. It is shown that the persistent current in this system induced by a magnetic flux depends sensitively on both the parity of this system and the size of the ring. Some new results are obtained and relevant underlying physics of this problem is discussed. (C) 2002 Elsevier Science B.V. All rights reserved. |
