The observed effect is ascribed to a so-far overlooked contribution to the g factor that stems from the mixing between heavy- and light-hole wave functions. We show that the relative displacement between the confined heavy- and light-hole states, occurring upon application of the electric field, alters their mixing strength leading to a strong nonmonotonic modulation of the g factor."}],"acknowledgement":"We acknowledge financial support from the Nanosciences Foundation (Grenoble, France), DOE under Contract No. DEFG02-08ER46482 (Yale), the Agence Nationale de la Recherche, and the European Starting Grant.
