Electric-dipole-induced spin resonance in quantum dots

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...

Interaction-induced spin polarization in quantum dots.

The electronic states of lateral many-electron quantum dots in high magnetic fields are analyzed in terms of energy and spin. In a regime with two Landau levels in the dot, several Coulomb-blockade peaks are measured. A zigzag pattern is found as it is known from the Fock-Darwin spectrum. However, only data from Landau level 0 show the typical spin-induced bimodality, whereas features from Land...

Nuclear-spin-induced oscillatory current in spin-blockaded quantum dots.

We show experimentally that electron transport through GaAs-based double quantum dots can be affected by ambient nuclear spin states in a certain regime where transport is blocked in the absence of electron spin flip. Current through the dots oscillates in time with a period up to 200 s depending on magnetic field. Oscillation is quenched by application of a continuous wave ac magnetic field wh...
