Description:
Author(s): S. Takada, M. Yamamoto, C. Bäuerle, A. Alex, J. von Delft, A. Ludwig, A. D. Wieck, and S. Tarucha We study the transmission phase shift across a Kondo correlated quantum dot in a GaAs heterostructure at temperatures below the Kondo temperature ( T 〈 T K ) , where the phase shift is expected to show a plateau at π / 2 for an ideal Kondo singlet ground state. Our device is tuned such that the ratio Γ / U … [Phys. Rev. B 94, 081303(R)] Published Fri Aug 19, 2016
