Using a frequency-comb nuclear magnetic resonance spectroscopy technique it is possible to probe the fluctuations in the nuclear spin bath of a self-assembled quantum dot and reveal long nuclear spin correlation times over one second. 
Quantum dots: Nuclear spins get a comb-over
A frequency comb technique used in NMR spectroscopy reveals the dynamics of the nuclear spin bath in self-assembled quantum dots.
Dynamical suppression of fluctuations in an interacting nuclear spin bath of a self-assembled quantum dot using multiple pulse nuclear magnetic resonance
Electron spin qubit coherence in quantum dots is ultimately limited by random nuclear spin bath fluctuations. Here we aim to eliminate this randomness by making spin bath evolution deterministic. We
Quantum dot spin coherence governed by a strained nuclear environment
Spin coherence can be improved by applying large magnetic fields and reducing strain inhomogeneity by recovering the intrinsic coherence time set by the interaction with the inhomogeneously strained nuclear bath.

In III-V semiconductor nano-structures the electron and nuclear spin dynamics are strongly coupled. Both spin systems can be controlled optically. The nuclear spin dynamics is widely studied, but
Measurement of the spin temperature of optically cooled nuclei and GaAs hyperfine constants in GaAs/AlGaAs quantum dots.
This work measures the nuclear polarization in GaAs/AlGaAs quantum dots with high accuracy using a new approach enabled by manipulation of the nuclear spin states with radiofrequency pulses and finds that optically cooled nuclei are well described within a classical spin temperature framework.
Rapid survey of nuclear quadrupole resonance by broadband excitation with comb modulation and dual-mode acquisition.

It is demonstrated that strain-induced quadrupolar interactions make nuclear spin fluctuations much slower compared with lattice-matched GaAs/AlGaAs structures, and can potentially be used to engineer optically active III-V semiconductor spin-qubits with a nearly noise-free nuclear spin bath, previously achievable only in nuclear spin-0 semiconductors.
