Suppression of nuclear spin fluctuations in an InGaAs quantum dot ensemble by GHz-pulsed optical excitation

E. Evers et al.

Summary: The team demonstrated the coherent electron spin dynamics of a group of quantum dots driven by periodic optical excitation, achieving a single Larmor precession mode and directed dynamic nuclear polarization. The highly periodic optical excitation showed potential in reducing nuclear spin fluctuations, providing a robust nuclear environment for subsequent electron spin manipulation.

Nuclear-induced frequency focusing and Overhauser field distributions in periodically pumped gallium arsenide

Michael J. Dominguez et al.

Summary: Periodic optical pumping of semiconductor systems such as gallium arsenide allows for insight into the spin dynamics and coupling of electrons and nuclei. Nuclear-induced frequency focusing is observed when spin-polarized nuclei alter the electron's Larmor precession frequency, approaching discrete values. By extending the model to account for a distribution of electron spins with different Overhauser fields, the study was able to reproduce various phenomena observed in Kerr rotation, including peak deformations and changes in rotation amplitude.

Shielding of external magnetic field by dynamic nuclear polarization in (In,Ga)As quantum dots

E. Evers et al.

Summary: The dynamics of the coupled electron-nuclear spin system in (In,Ga)As/GaAs quantum dots is studied through periodic optical excitation, resulting in dynamic nuclear polarization that shields the QD electrons from external magnetic fields. By modeling the effect using a magnetic field-dependent polarization rate, a strategy for adjusting the nuclear polarization is proposed through detuning between optical excitation and electronic transition in addition to tuning the magnetic field.
