Nuclear spin coherence in a quantum wire
A. Corcoles, C. J. B. Ford, M. Pepper +3
We have observed millisecond-long coherent evolution of nuclear spins in a quantum wire at 1.2 K. Local, all-electrical manipulation of nuclear spins is achieved by dynamic nuclear…
Kondo physics versus spin gap physics in fully spin-split quantum wires
F. Sfigakis, C. J. B. Ford, M. Pepper +4
Linear and nonlinear transport of quantum wires is investigated at a magnetic field where spin-split one-dimensional (1D) subbands are equidistant in energy. In this seldom-studied…
Electron interactions in an antidot in the integer quantum Hall regime
H. -S. Sim, M. Kataoka, C. J. B. Ford
A quantum antidot, a submicron depletion region in a two-dimensional electron system, has been actively studied in the past two decades, providing a powerful tool for understanding…
Energy-dependent tunnelling from few-electron dynamic quantum dots
M. R. Astley, M. Kataoka, C. J. B. Ford +6
We measure the electron escape-rate from surface-acoustic-wave dynamic quantum dots (QDs) through a tunnel barrier. Rate-equations are used to extract the tunnelling rates, which c…
Probing e-e interactions in a periodic array of GaAs quantum wires
Y. Jompol, C. J. B. Ford, I. Farrer +5
We present the results of non-linear tunnelling spectroscopy between an array of independent quantum wires and an adjacent two-dimensional electron gas (2DEG) in a double-quantum-w…
Geometric Suppression of Single-Particle Energy Spacings in Quantum Antidots
L. C. Bassett, C. P. Michael, C. J. B. Ford +4
Quantum Antidot (AD) structures have remarkable properties in the integer quantum Hall regime, exhibiting Coulomb-blockade charging and the Kondo effect despite their open geometry…
