| Abstract: | The time evolution property of the atomic information entropy squeezing in Bose-Einstein condensate atom interacting with the Schrödinger cat-states are studied by means of quantum theory. The results indicate that when phase angle is at between the two coherent states in the Schrödinger cat state, atomic information entropy squeezing will shows squeezing effects alternately with the variation of the intensity of optical field and coupling coefficients. |
