Abstract: We demonstrate that bistability of the nuclear spin polarization in opticallypumped semiconductor quantum dots is a general phenomenon possible in dots witha wide range of parameters. In experiment, this bistability manifests itselfvia the hysteresis behavior of the electron Zeeman splitting as a function ofeither pump power or external magnetic field. In addition, our theory predictsthat the nuclear polarization can strongly influence the charge dynamics in thedot leading to bistability in the average dot charge.
