Boson-fermion mappings for odd systems from supercoherent states
arXiv:nucl-th/9303026 · doi:10.1103/PhysRevC.48.2313
Abstract
We extend the formalism whereby boson mappings can be derived from generalized coherent states to boson-fermion mappings for systems with an odd number of fermions. This is accomplished by constructing supercoherent states in terms of both complex and Grassmann variables. In addition to a known mapping for the full so(2+1) algebra, we also uncover some other formal mappings, together with mappings relevant to collective subspaces.
