Spin-orbit qubit in a semiconductor nanowire
S. Nadj-Perge, S. M. Frolov, E. P. A. M. Bakkers +1
Motion of electrons can influence their spins through a fundamental effect called spin-orbit interaction. This interaction provides a way to electrically control spins and as such…
Spin-orbit anisotropy measured using ballistic spin resonance
W. W. Yu, S. M. Frolov, S. Luescher +2
Spin relaxation can be greatly enhanced in narrow channels of two-dimensional electron gas due to ballistic spin resonance, which is mediated by spin-orbit interaction for trajecto…
Measurement of spin-dependent conductivities in a two-dimensional electron gas
H. Ebrahimnejad, Y. Ren, S. M. Frolov +3
Spin accumulation is generated by injecting an unpolarized charge current into a channel of GaAs two-dimensional electron gas subject to an in-plane magnetic field, then measured i…
Zero-bias Anomaly of Quantum Point Contacts in the Low-Conductance Limit
Y. Ren, W. W. Yu, S. M. Frolov +2
Most quantum point contacts (QPCs) fabricated in high-mobility 2D electron gases show a zero-bias conductance peak near pinchoff, but the origin of this peak remains a mystery. Pre…
Numerical study of resonant spin relaxation in quasi-1D channels
S. Luescher, S. M. Frolov, J. A. Folk
Recent experiments demonstrate that a ballistic version of spin resonance, mediated by spin-orbit interaction, can be induced in narrow channels of a high-mobility GaAs two-dimensi…
Disentangling the effects of spin-orbit and hyperfine interactions on spin blockade
S. Nadj-Perge, S. M. Frolov, J. W. W. van Tilburg +5
We have achieved the few-electron regime in InAs nanowire double quantum dots. Spin blockade is observed for the first two half-filled orbitals, where the transport cycle is interr…
