Interplay between Orbital Magnetic Moment and Crystal Field Symmetry: Fe atoms on MgO
S. Baumann, F. Donati, S. Stepanow +15
We combine density functional theory, x-ray magnetic circular dichroism, multiplet calculations, and scanning tunneling spectroscopy to assess the magnetic properties of Fe atoms a…
Quantum Phase Transitions in Quantum Dots
I. G. Rau, S. Amasha, Y. Oreg +1
This review article describes theoretical and experimental advances in using quantum dots as a system for studying impurity quantum phase transitions and the non-Fermi liquid behav…
Observation of the SU(4) Kondo state in a double quantum dot
A. J. Keller, S. Amasha, I. Weymann +6
Central to condensed matter physics are quantum impurity models, which describe how a local degree of freedom interacts with a continuum. Surprisingly, these models are often unive…
Nonsaturating Dephasing Time at Low Temperature in an Open Quantum Dot
I. G. Rau, S. Amasha, M. Grobis +3
We report measurements of the electron dephasing time extracted from the weak localization (WL) correction to the average conductance in an open AlGaAs/GaAs quantum dot from 1 K to…
Pseudospin-Resolved Transport Spectroscopy of the Kondo Effect in a Double Quantum Dot
S. Amasha, A. J. Keller, I. G. Rau +5
We report measurements of the Kondo effect in a double quantum dot (DQD), where the orbital states act as pseudospin states whose degeneracy contributes to Kondo screening. Standar…
Coulomb Blockade in an Open Quantum Dot
S. Amasha, I. G. Rau, M. Grobis +3
We report the observation of Coulomb blockade in a quantum dot contacted by two quantum point contacts each with a single fully-transmitting mode, a system previously thought to be…
