The time evolution of operators and state vectors in quantum mechanics can be
expressed in different representations. The SCHRÖDINGER, the interaction, and the
HEISENBERG representations are useful in analyzing the second-quantized
form of the SCHRÖDINGER equation. The HAMILTONian is assumed to be
of the form (see (3.1))

contains all the interactions, such as
carrier-carrier, carrier-phonon, impurity scattering, and so forth.
