Transmission Phase of a Quantum Dot with Kondo Correlation near the Unitary Limit
Transmission Phase of a Quantum Dot with Kondo Correlation near the Unitary Limit
The complex transmission amplitude of a quantum dot (QD) with Kondo correlation was measured near the unitary limit. The transmission phase was observed to evolve almost linearly over a range of about 1.5 pi when the Fermi energy was scanned through a spin degenerate energy level of the QD. Surprisingly, …
