The Coulomb-interaction-induced breaking of the Aufbau principle for   hole charging of InGaAs/GaAs quantum dots
  The so called "incomplete hole shell filling" phenomenon, that is the breaking of the Aufbau principle was reported by D. Reuter et al., [Phys. Rev. Lett. 94, 026808] in the hole charging spectra of quantum dot when results were interpreted in context of s/p/d shell system - typical for electrons. We report an example of inter-particle-interaction induced Aufbau principle violation even if it is applied to one-particle Kohn-Luttinger eigenstates. We present a k-dot-p/configuration-interaction study that concerns multiple holes confined in InGaAs/GaAs self-assembled cylindrical quantum dot. Eigenenergies and eigenvectors of up to six hole ground states were obtained - along with corresponding one-hole orbital occupations - and discussed in context of the Aufbau principle.
