Supplementary Information: Electric Dipole Induced Spin Resonance in Disordered Semiconductors

Here, we give a more detailed account of the evaluation of the polarization S (ω), Eq. (A11) of the Article, in terms of the spin-spin and the spin-momentum terms, X , Y , respectively, and the spin vertex correction Σ. The simultaneous presence of the internal and external fields, α(p × ez) and b0, resp., breaks the symmetry in orbital space such that no closed analytical expression for the in...

Electric field induced nuclear spin resonance mediated by oscillating electron spin domains in GaAs-based semiconductors.

We demonstrate an alternative nuclear spin resonance using a radio frequency (rf) electric field [nuclear electric resonance (NER)] instead of a magnetic field. The NER is based on the electronic control of electron spins forming a domain structure. The rf electric field applied to a gate excites spatial oscillations of the domain walls and thus temporal oscillations of the hyperfine field to n...

Controlling a nanowire spin-orbit qubit via electric-dipole spin resonance.

A semiconductor nanowire quantum dot with strong spin-orbit coupling (SOC) can be used to achieve a spin-orbit qubit. In contrast to a spin qubit, the spin-orbit qubit can respond to an external ac electric field, an effect called electric-dipole spin resonance. Here we develop a theory that can apply in the strong SOC regime. We find that there is an optimal SOC strength η(opt)=√2/2, where the...

Theory for spin diffusion in disordered organic semiconductors.

We present a theory for spin diffusion in disordered organic semiconductors, based on incoherent hopping of a charge carrier and coherent precession of its spin in an effective magnetic field, composed of the random hyperfine field of hydrogen nuclei and an applied magnetic field. From Monte Carlo simulations and an analysis of the waiting-time distribution of the carrier we predict a surprisin...

Dephasing due to Nuclear Spins in Large-Amplitude Electric Dipole Spin Resonance.

We analyze effects of the hyperfine interaction on electric dipole spin resonance when the amplitude of the quantum-dot motion becomes comparable or larger than the quantum dot's size. Away from the well-known small-drive regime, the important role played by transverse nuclear fluctuations leads to a Gaussian decay with characteristic dependence on drive strength and detuning. A characterizatio...
