Relaxation of Shallow Donor Electron Spin due to Interaction with Nuclear Spin Bath

Semion Saykin, Dima Mozyrsky, Vladimir Privman

We study the low-temperature dynamics of a shallow donor, e.g., ${}^{31}$P, impurity electron spin in silicon, interacting with the bath of nuclear spins of the ${}^{29}$Si isotope. Fo…
