摘要：
Resonant tunneling through an open quantum dot in the Coulomb blockade regime T << e(2)/C-0 is studied numerically using the path-integral Monte Carlo method. The quantum dot is connected to two bulk leads by single-mode point contacts. We consider on-site repulsion between electrons and analyze its influence on the resonant conductance. Our numerical results exhibit power-law dependence of the peak width and the phase transition between perfect conductor and insulator, which is consistent with the analytical results.
