Cotunneling drag effect in Coulomb-coupled quantum dots
A. J. Keller, J. S. Lim, David Sánchez +5
In Coulomb drag, a current flowing in one conductor can induce a voltage across an adjacent conductor via the Coulomb interaction. The mechanisms yielding drag effects are not alwa…
Universal Fermi liquid crossover and quantum criticality in a mesoscopic device
A. J. Keller, L. Peeters, C. P. Moca +5
Quantum critical systems derive their finite temperature properties from the influence of a zero temperature quantum phase transition. The paradigm is essential for understanding u…
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…
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…
