Query: Influcence of the nuclear electric quadrupolar interaction on the
  coherence time of hole- and electron-spins confined in semiconductor quantum
  dots   The real-time spin dynamics and the spin noise spectra are calculated for p
and n-charged quantum dots within an anisotropic central spin model extended by
additional nuclear electric quadrupolar interactions (QC) and augmented by
experimental data studied using identical excitation conditions. Using
realistic estimates for the distribution of coupling constants including an
anisotropy parameter, we show that the characteristic long time scale is of the
same order for electron and hole spins strongly determined by the QC even
though the analytical form of the spin decay differs significantly consistent
with our measurements. The low frequency part of the electron spin noise
spectrum is approximately $1/3$ smaller than those for hole spins as a
consequence of the spectral sum rule and the different spectral shapes. This is
confirmed by our experimental spectra measured on both types of quantum dot
ensembles in the low power limit of the probe laser.
