    "abstract": "A new concise method is presented for the calculation of the ground-state\nenergy of the electromagnetic field and matter field interacting system. With\nthe assumption of squeezed-like state, a new vacuum state is obtained for the\ninteracting system. The energy of the new vacuum state is lower than that given\nby the second-order perturbation theory in existing theories. In our theory,\nthe Casimir effect is attributed neither to the quantum fluctuation in the\nzero-point energy of the genuine electromagnetic field nor to that in the\nzero-point energy of the genuine matter field, but to that in the vacuum state\nof the interacting system. Both electromagnetic field and matter field are\nresponsible for the Casimir effect.",
