Measurement of Temporal Correlations of the Overhauser Field in a Double Quantum Dot
D. J. Reilly, J. M. Taylor, E. A. Laird +4
In quantum dots made from materials with nonzero nuclear spins, hyperfine coupling creates a fluctuating effective Zeeman field (Overhauser field) felt by electrons, which can be a…
Dynamic Nuclear Polarization with Single Electron Spins
J. R. Petta, J. M. Taylor, A. C. Johnson +5
We polarize nuclear spins in a GaAs double quantum dot by controlling two-electron spin states near the anti-crossing of the singlet (S) and m_S=+1 triplet (T+) using pulsed gates.…
Fast Single-Charge Sensing with an rf Quantum Point Contact
D. J. Reilly, C. M. Marcus, M. P. Hanson +1
We report high-bandwidth charge sensing measurements using a GaAs quantum point contact embedded in a radio frequency impedance matching circuit (rf-QPC). With the rf-QPC biased ne…
Hyperfine-mediated gate-driven electron spin resonance
E. A. Laird, C. Barthel, E. I. Rashba +3
An all-electrical spin resonance effect in a GaAs few-electron double quantum dot is investigated experimentally and theoretically. The magnetic field dependence and absence of ass…
Drift and Diffusion of Spins Generated by the Spin Hall Effect
N. P. Stern, D. W. Steuerman, S. Mack +2
Electrically generated spin accumulation due to the spin Hall effect is imaged in n-GaAs channels using Kerr rotation microscopy, focusing on its spatial distribution and time-aver…
Current Noise in Quantum Point Contacts
L. DiCarlo, Yiming Zhang, D. T. McClure +6
We present measurements of current noise in quantum point contacts as a function of source-drain bias, gate voltage, and in-plane magnetic field. At zero bias, Johnson noise provid…
