Erbe, Björn and Schliemann, John (2010) Hyperfine induced spin and entanglement dynamics in double quantum dots: A homogeneous coupling approach. Phys. Rev. B 81, p. 235324.
We investigate hyperfine induced electron spin and entanglement dynamics in a system of two quantum dot spin qubits. We focus on the situation of zero external magnetic field and concentrate on approximation-free theoretical methods. We give an exact solution of the model for homogeneous hyperfine coupling constants (with all coupling coefficients being equal) and varying exchange coupling, and ...
