Dynamical entanglement of vibrations in small molecules through an analytically algebraic approach
Yan Liu, Yujun Zheng, Weiyi Ren, Shiliang Ding · Physical Review A · 2008
We study the dynamical entanglement of vibrations in small molecules by employing algebraic models. We analytically obtain the linear entropy, von Neumann entropy, and the Lyapunov function for the integrable dimer and realistic small molecules for both initial Fock states and coherent states. The contributions of states to the dynamical entropy are also investigated.
