The semiconductor Bloch equations (SBEs) have proven to be an efficient tool to describe linear and non-linear optical responses of semiconductor lasers and LEDs taking into account many-body effects such as electron-electron interactions, electron-phonon scattering, and Auger recombination. Their success in simulating the ultrafast spectroscopy of III-V semiconductor materials motivates recent attempts to apply them for perovskites, 2D semiconductor materials, and organic semiconductors. In this tutorial, we will discuss the limitations of SBEs and report on the recent progress in applying them for 2D semiconductors such as graphene.
