Correlation Approximation

The electron spin decoherence by nuclear spins in semiconductor quantum dots is caused by quantum entanglement between the electron and the nuclei. The many-body dynamics problem of the interacting nuclear spins can be solved with the pair-correlation approximation which treats the nuclear spin flip-flops as mutually independent. The nuclear spin dynamics can be controlled by simply flipping the electron spin so that the electron is disentangled from the nuclei and hence its lost coherence is restored.

<pre>We present a new protocol for predicting the phase memory decay/decoherence profiles of electron spin of organic radical molecules embedded in glassy organic solvent matrices at low temperatures. In this approach the microscopic configurations of various glassy solvent matrix systems with nitroxyl radical embedded are prepared using molecular dynamics simulations and simulated annealing. Nuclear spin bath models of embedded radical electron spin decoherence are built for each sample obtained from these configurations. Decoherence profiles under various dynamical decoupling pulse sequences are obtained from these nuclear spin bath models using the cluster correlation expansion method. Our results reflect well the long range disordering nature of glassy structures and show good agreement with their experimental counterparts reported in literature for a variety of organic solvents.</pre>
