摘要：

Many electrons tunneling through strong Hubbard interacting quantum dots in applied magnetic field is studied numerically. It is found that the oscillations in conductance and magnetization exhibit a class of new universal quantum oscillations. In particular, the periodic conductance oscillations as a function of magnetic field are predicted and agree qualitatively with experimental measurements. (C) 2002 Elsevier Science B.V.
