Row coupling in an interacting quasi-one-dimensional quantum wire investigated using transport measurements
L. W. Smith, W. K. Hew, K. J. Thomas +5
We study electron transport in quasi-one-dimensional wires at relatively weak electrostatic confinements, where the Coulomb interaction distorts the ground state, leading to the bi…
Microwave-Driven Transitions in Two Coupled Semiconductor Charge Qubits
K. D. Petersson, C. G. Smith, D. Anderson +3
We have studied interactions between two capacitively coupled GaAs/AlGaAs few-electron double quantum dots. Each double quantum dot defines a tunable two-level system, or qubit, in…
Highly enhanced thermopower in two-dimensional electron systems at milliKelvin temperatures
Srijit Goswami, Christoph Siegert, Matthias Baenninger +4
We report experimental observation of an unexpectedly large thermopower in mesoscopic two-dimensional (2D) electron systems on GaAs/AlGaAs heterostructures at sub-Kelvin temperatur…
Parallel quantized charge pumping
S. J. Wright, M. D. Blumenthal, M. Pepper +4
Two quantized charge pumps are operated in parallel. The total current generated is shown to be far more accurate than the current produced with just one pump operating at a higher…
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…
