Analytical Solution of Electron Spin Decoherence Through Hyperfine Interaction in a Quantum Dot
Changxue Deng, Xuedong Hu
We analytically solve the {\it Non-Markovian} single electron spin dynamics due to hyperfine interaction with surrounding nuclei in a quantum dot. We use the equation-of-motion met…

Selective Dynamic Nuclear Spin Polarization in Spin-Blocked Double-Dot
Changxue Deng, Xuedong Hu
We study the mechanism of dynamical nuclear spin polarization by hyperfine interaction in spin-blocked double quantum dot system. We calculate the hyperfine transition rates and so…
