The strategy of the previous chapter to derive quantum drift-diffusion equations can be generalized. Similar to the semi-classical diffusive limit, we impose several moment constraints, leading to a system of diffusive equations. In this chapter, we explain the general strategy and consider in more detail a specific quantum model, consisting of the balance equations of mass and energy, the so-called quantum energy-transport equations.
