The hydrodynamic moment equations for a quantum system described by a two-band K.P Hamiltonian are derived. In the case of pure states, it is proved that the order-0 and order-1 moment equations yield a closed system which is the two-band analogue of Madelung's fluid equations.

Abstract
The hydrodynamic moment equations for a quantum system described by a two-band K.P Hamiltonian are derived. In the case of pure states, it is proved that the order-0 and order-1 moment equations yield a closed system which is the two-band analogue of Madelung's fluid equations.
