The semiconductor Bloch equations (SBEs) describe exciton dynamics accounting for Coulomb interactions, but neglect the transfer of momentum between a driving light field and the excitons. We derive tilted SBEs that account for the momentum transfer, and demonstrate their use for calculating exciton dynamics to all orders in the field amplitude.
