Dynamic response of a spin-1/2 Kondo singlet
Bryan Hemingway, Stephen Herbert, Michael Melloch +1
We present a study of spin 1/2 Kondo singlets in single electron transistors under a microwave frequency bias excitation. We compare time-averaged conductance to predicted univ…
A quantitative study of spin-flip co-tunneling transport in a quantum dot
Tai-Min Liu, Anh T. Ngo, Bryan Hemingway +4
We report detailed transport measurements in a quantum dot in a spin-flip co-tunneling regime, and a quantitative comparison of the data to microscopic theory. The quantum dot is f…
Anamolous conductance plateau in an asymmetrically biased InAs/InAlAs quantum point contact
P. P. Das, K. B. Chetry, N. Bhandari +4
The appearance and evolution of an anomalous conductance plateau at 0.4 (in units of 2e2/h) in an In0.52Al0.48As/InAs quantum point contact (QPC), in the presence of lateral spin-o…
Magnetic-Field-Induced Crossover to a Nonuniversal Regime in a Kondo Dot
Tai-Min Liu, Bryan Hemingway, Steven Herbert +2
We have measured the magnetic splitting, , of a Kondo peak in the differential conductance of a Single-Electron Transistor while tuning the Kondo temperature, , along two…
Magnetic Splitting of the Zero Bias Peak in a Quantum Point Contact with a Variable Aspect Ratio
Tai-Min Liu, Bryan Hemingway, Andrei Kogan +2
We report a zero-bias peak in the differential conductance of a Quantum Point Contact (QPC), which splits in an external magnetic field. The peak is observed over a range of device…
Finite-Size Effects and Dynamical Scaling in Two-Dimensional Josephson Junction Arrays
J. Holzer, R. S. Newrock, C. J. Lobb +2
In recent years many groups have used Fisher, Fisher, and Huse (FFH) dynamical scaling to investigate and demonstrate details of the superconducting phase transition. Some attentio…
