Phys. Rev. Lett. 96, 186602 (2006) [4 pages]Theory of Phonon-Induced Spin Relaxation in Laterally Coupled Quantum DotsReceived 30 December 2005; published 8 May 2006 Phonon-induced spin relaxation in coupled lateral quantum dots in the presence of spin-orbit coupling is calculated. The calculation for single dots is consistent with experiment. Spin relaxation in double dots at useful interdot couplings is dominated by spin-hot spots that are strongly anisotropic. Spin-hot spots are ineffective for a diagonal crystallographic orientation of the dots with a transverse in-plane field. This geometry is proposed for spin-based quantum information processing. © 2006 The American Physical Society URL:
