UNSPECIFIED (1991) THE ROLE OF SPIN IN THE DEVELOPMENT OF COHERENT STRUCTURES IN MANY-BODY SYSTEMS. PHYSICS LETTERS A, 155 (2-3). pp. 107-112. ISSN 0375-9601Full text not available from this repository.
Spin components have been explicitly included in an accurate analytical approach for the study of coherent structures in many-body systems. Equations of motion for annihilators and creators are transformed into non-linear equations of motion for a spin-dependent quantum field. It is demonstrated, using commutation relations for the quantum field operators, that spin-up, psi+, and spin-down, psi-, fields may be decoupled. The equation of motion for psi+ is shown to have a form identical to the equation of motion for psi+ which, in turn, is equivalent to that for a field with no specific spin component. The latter equations have the same form for both bosons and fermions.
