| 英文摘要 | Strong electron and spin correlations are studied in parallel-coupled double quantum dots with interdot spin superexchange J. In the Kondo regime with degenerate dot energy levels, coherent transport occurs at zero temperature, where two entangled (bonding and antibonding) resonances are formed near the Fermi energy. When increasing J or the dot-lead parallel-coupling asymmetry ratio Gamma(2)/Gamma(1), a swap between two entangled resonances occurs and the line shapes of the transmission are interchanged. The linear conductance shows a peak at the critical values. Such a peculiar effect with the virtue of many-body coherence may be useful in future quantum computing. |
