Dynamical Evolution and Entanglement in a Nonlinear Interacting System
Sun Hui-Ying, Huang Xiao-Li, Yi Xue Xi · Chinese Physics Letters · 2009
We investigate a few features of entanglement of two types of particles coupled through a nonlinear interaction. It is shown that the entanglement created by the nonlinear interaction can reflect nonlinearity of the system. Possible observation of our prediction in a double-well trapped Bose–Einstein condensate is discussed.
