| Abstract: | In this paper atomic squeezing properties of Bose-Einstein Condensate in electromagnetically induced transparency are studied analytically and numerically. The dependence of single-mode squeezing and two-mode squeezing on the parameters is investigated in detail. It is found that the degree of single-mode squeezing can be enhanced by increasing the initial intensity of the field in this mode and decreasing the interaction between two modes and that of two-mode squeezing can be enhanced by increasing the initial intensity in both modes and the interaction between two modes. |
