When the dimer is in a bound state, the ground state wavefunction is a product of two-mode squeezed states and an exact expression for the R{\'e}nyi entanglement entropy is obtained. The entanglement entropy decays as a power of the separation distance between the dipoles and is a maximum at a critical length determined by the effective Bohr radius of the charge and the confinement length of the trapping potential.}, url = {https://paperview.spp-online.org/proceedings/article/view/SPP-2018-PB-53}, author = {Mignon Frances A.
