Nonmonotonic spin relaxation and decoherence in graphene quantum dots with spin-orbit interactions
We investigate the spin relaxation and decoherence in a single-electron graphene quantum dot with Rashba and intrinsic spin-orbit interactions. We derive an effective spin-phonon Hamiltonian via the Schrieffer-Wolff transformation in order to calculate the spin relaxation time ${T}_{1}$ and decoherence time ${T}_{2}$ within the framework of the Bloch-Redfield theory.
