Quons Restricted to the Antisymmetric Subspace: Formalism and Applications
S. S. Avancini, F. F. de Souza Cruz, J. R. Marinelli +2
In this work we develop a formalism to treat quons restricted to the antisymmetric part of their many-body space. A model in which a system of identical quons interact through a pa…
The q-Deformed NJL Model "Revisited"
S. S. Avancini, J. R. Marinelli, D. P. Menezes +1
In this work we investigate the chiral symmetry breaking in the q-deformed version of the NJL Model and its consequent mass generation mechanism . We show that the deformation of t…
Exact Q-Deformed Dyson Expansion for the Nuclear J=5/2 Shell
S. S. Avancini, J. R. Marinelli, D. P. Menezes +2
The quon algebra, which interpolates between the Bose and Fermi algebras and depends on a free paramenter , is used to generate a deformed Dyson boson expansion of the quadrupol…
q- Deformed Boson Expansions
S. S. Avancini, F. F. de Souza Cruz, J. R. Marinelli +2
A deformed boson mapping of the Marumori type is derived for an underlying algebra. As an example, we bosonize a pairing hamiltonian in a two level space, for which an exac…
