SDG fermion-pair algebraic SO(12) and Sp(10) models and their boson realizations.

P. Navrátil, H. B. Geyer, J. Dobaczewski

It is shown how the boson mapping formalism may be applied as a useful manybody tool to solve a fermion problem. This is done in the context of generalized Ginocchio models for which we introduce S-, D-, and G-pairs of fermions and subsequently construct the sdg-boson realizations of the generalized Dyson type. The constructed SO(12) and Sp(10) fermion models are solved beyond the explicit symmetry limits. Phase transitions to rotational structures are obtained, also in situations where there is no underlying SU(3) symmetry.

Exactly solvable fermion-boson mapping representations

Osvaldo Civitarese, M. Reboiro

The Holstein-Primakoff boson mapping technique is applied to transform Hamiltonians defined in terms of the generators of the SU(2) and Sp(4) groups. These solvable models consist of a pair of fermions which interact with hard bosons. It is shown that the mapping to ideal bosons preserves the algebra and that exact matrix elements of the original fermionic Hamiltonian can be reconstructed from the bosonic representation.
