Energy dependence of the entanglement entropy of composite boson (quasiboson) systems
Energy dependence of the entanglement entropy of composite boson (quasiboson) systems
Bipartite composite boson (quasiboson) systems, which admit realization in terms of deformed oscillators, were considered in our previous paper from the viewpoint of entanglement characteristics. These characteristics, including entanglement entropy and purity, were expressed through the relevant deformation parameter for different quasibosonic states. On the other hand, it is of …
