Abstract

The effect of electron-electron Hubbard interaction on magnetoconductance fluctuations in disordered quantum ring is studied by using a recursive real-space Green's function technique in tight-binding model. The present numerical results improve previous theoretical results for the magnetoconductance fluctuations as a function of magnetic flux compared with experiments. Several new anomalous phenomena at low temperatures, which do not survive at high temperatures, are obtained.
