Abstract: | Composite bosons (or quasibosons), as recently proven, are realizable by deformed oscillators and due to that can be effectively treated as particles of non-standard statistics (deformed bosons). This enables us to study quasiboson states and their inter-component entanglement aspects using the well-developed formalism of deformed oscillators. We prove that the internal entanglement characteristics for single two-component quasiboson are determined completely by the parameter(s) of deformation. The bipartite entanglement characteristics are generalized and calculated for arbitrary multi-quasiboson (Fock, coherent, etc.) states and expressed through deformation parameter. |
