Entanglement sharing in \(E\otimes\epsilon\) Jahn-Teller model in the presence of a magnetic field

We discuss the ground state entanglement of the \(E\otimes\epsilon\) Jahn-Teller model in the presence of a strong transverse magnetic field as a function of the vibronic coupling strength. A complete characterization is given of the phenomenon of entanglement sharing in a system composed by a qubit...

Summary:We discuss the ground state entanglement of the \(E\otimes\epsilon\) Jahn-Teller model in the presence of a strong transverse magnetic field as a function of the vibronic coupling strength. A complete characterization is given of the phenomenon of entanglement sharing in a system composed by a qubit coupled to two bosonic modes. Using the residual \(I\)-tangle, we find that three-partite entanglement is significantly present in the system in the parameter region near the bifurcation point of the corresponding classical model.
