From the Schrodinger equations of the Bose-Fermi mixture in a double well coupled with a cavity,the time evolution expressions for the particle and the photon operator were given.An effective classical Hamiltonian for this system was derived,and its dynamics was investigated from the perspective of the phase portrait.It was shown that the strong condensate-cavity interplay did alter the dynamics of the system drastically.We found that the evolution of the relative number difference could be controlled by the interaction between fermions and the ones between bosons and fermions,respectively,and that the coupling with the cavity could make the system appear with more fixed points.The motional mode increased and the chaos could be enhanced accordingly.
