Dynamical self-quenching of spin pumping into double quantum dots.
Nuclear spin polarization can be pumped into spin-blockaded quantum dots by multiple Landau-Zener passages through singlet-triplet anticrossings. By numerical simulations of realistic systems with 10(7) nuclear spins during 10(5) sweeps, we uncover a mechanism of dynamical self-quenching which results in a fast saturation of the nuclear polarization under stationary pumping. This is caused by s...
متن کاملKondo-model for quantum-dots with spin-orbit coupling
Cotunneling through a spin-orbit coupled quantum dot Starting from the Anderson model for a quantum dot, with Rashba type spinorbit (SO) interactions, coupled to two metallic electrodes, we derive an effective low-energy Hamiltonian describing the dynamical spin-fluctuations, i.e. the cotunneling processes, which remain in the Coulomb blockade regime. This projection to the low-energy states of...
متن کاملSpin relaxation due to deflection coupling in nanotube quantum dots
We consider relaxation of a single-electron spin in a nanotube quantum dot due to its coupling to flexural phonon modes, and identify a new spin-orbit-mediated coupling between the nanotube deflection and the electron spin. This mechanism dominates other spin-relaxation mechanisms in the limit of small energy transfers. Due to the quadratic dispersion law of long-wavelength flexons, q2, the den...
متن کاملSpin-orbit coupling and anisotropy of spin splitting in quantum dots.
In lateral quantum dots, the combined effect of both Dresselhaus and Bychkov-Rashba spin-orbit coupling is equivalent to an effective magnetic field +/- B(SO) which has the opposite sign for s(z)= +/- 1/2 spin electrons. When the external magnetic field is perpendicular to the planar structure, the field B(SO) generates an additional splitting for electron states as compared to the spin splitti...
متن کاملSpin relaxation in quantum dots
Results are given for spin relaxation in quantum dots due to acoustic phonon-assisted flips of single spins at low temperatures. The dominant spin relaxation processes for varying dot size, temperature, and magnetic field are identified. These processes are mediated by the spin-orbit interaction and are described within a generalized effective mass treatment. Particular attention is given to ph...
