Fermion and boson condensates in a QCD-inspired model Hamiltonian - art. no. 064303

The interaction between bi-fermionic and bosonic degrees of freedom is desc ribed by using an effective Hamiltonian inspired in QCD. The Dyson boson ma pping technique is utilized in conjunction with a coherent state basis to c onstruct energy landscapes in a multiparametric space. The appearance of fe rmionic and bosonic condensates is studied by minimizing the potential ener gy surface. The relationship between the domains of fermion and boson conde nsates and the order parameters of the model is discussed.
