We present a new method to derive transport equations for non-relativistic quantum manyparticle systems. This method uses an equation-of-motion technique and is applicable to interacting fermions and (or) bosons in arbitrary time-dependent external fields. Using a cluster expansion of the r-particle
Assuming the ground state wavefunction, #,, , of a boson fluid is known, and writing the excited state wavefunctions in the form F/J,, , a linear eigenvalue equation of the form l?F = tPF is obtained, where E0 + E is the excited state energy, E0 is the ground state energy, and His a non-hermitian op
