Rashba effect and magnetic field in quantum wires
Stefan Debald, Bernhard Kramer
We investigate the influence of a perpendicular magnetic field on the spectral and spin properties of a ballistic quasi-one-dimensional electron system with Rashba effect. The magn…
Spin-orbit-driven coherent oscillations in a few-electron quantum dot
Stefan Debald, Clive Emary
We propose an experiment to observe coherent oscillations in a single quantum dot with the oscillations driven by spin-orbit interaction. This is achieved without spin-polarised le…
Phonon Cavity Models for Quantum Dot Based Qubits
T. Vorrath, S. Debald, B. Kramer +1
Phonon cavities are believed to be the next step towards a control of dephasing in semiconductor quantum dot `qubits'. In this paper, we discuss two models for phonon cavities - a…
Control of Dephasing and Phonon Emission in Coupled Quantum Dots
S. Debald, T. Brandes, B. Kramer
We predict that phonon subband quantization can be detected in the non-linear electron current through double quantum dot qubits embedded into nano-size semiconductor slabs, acting…
Phonons and Phonon Confinement in Transport through Double Quantum Dots
S. Debald, T. Vorrath, T. Brandes +1
We calculate the electron-phonon interaction coefficients for surface acoustic waves and for phonons in free standing quantum wells. These are used to derive the inelastic current…
