We give conclusive experimental evidence that spin-dependent exciton±exciton interaction processes can be altered by directly modifying the spatial exciton structure applying an electric field. The previously observed energy splitting in spin-polarized, dense exciton gases can be varied by the elect

An analytical approach to the problem of the Wannier-Mott exciton in a semiconductor quantum well (QW) in the presence of external magnetic and electric fields is developed. The magnetic field is taken to lie in the heteroplanes while the electric field is directed perpendicular to the heteroplanes.
