In the absence of magnetic field, our results in single quantum dots agree well with the experiment by Borselli {\\em et al.} [Appl. Phys. Lett. {\\bf 98}, 123118 (2011)]. We identify the spin and valley configurations of the ground state in the experimental cases and give a complete phase-diagram-like picture of the ground state con","authors_text":"K. Shen, L.
