Transmission Phase of a Quantum Dot with Kondo Correlation Near the Unitary Limit
arXiv:cond-mat/0106469 · doi:10.1103/PhysRevLett.88.076601
Abstract
The complex transmission amplitude -- both magnitude and phase -- of a quantum dot (QD) with Kondo correlation was measured near the unitary limit. Contrary to previous phase measurements, performed far from this limit [Ji et al., Science 290, 779 (2000)], the transmission phase was observed to evolve linearly over a range of about 1.5 pi when the Fermi energy was scanned through a Kondo pair -- a pair of spin degenerate energy levels. Moreover, the phase in Coulomb blockade (CB) peak, adjancent to the Kondo pair, retained a memory of the Kondo correlation and did not exhibit the familiar behavior in the CB regime. These results do not agree with theoretical predictions, suggesting that a full explanation may go beyond the framework of the Anderson model.
