Query: Proposal for a Datta-Das transistor in the quantum Hall regime   We propose a resonant spin-field-effect transistor for chiral spin-resolved
edge states in the integer quantum Hall effect with Rashba spin-orbit
interaction. It employs a periodic array of voltage-controlled top gates that
locally modulate the Rashba spin-orbit interaction. Strong resonant spin-field
effect is achieved when the array periodicity matches the inverse of the
wave-vector difference of the two chiral states involved. Well-known techniques
of separately contacting the edge states make it possible to selectively
populate and read out the edge states, allowing full spin readout. The resonant
nature of the spin-field effect and the adiabatic character of the edge states
guarantee a high degree of robustness with respect to disorder. Our device
represents the quantum Hall version of the all-electrical Datta-Das spin-field
effect transistor.
