Entanglement storage by classical fixed points in the two-axis countertwisting model

We analyze a scheme for self-trapping of entangled state by classical stable fixed points in the two-axis counter-twisting model. A characteristic feature of the two-axis counter-twisting Hamiltonian is the existence of the four stable center and two unstable saddle fixed points in their mean-field...
