Atomic Squeezing in a M Two-Level Atoms System

The atomic squeezing in a system of M two level atoms interacting with a coherent radiation of single mode is analyzed. The time dependent squeezing factor S has been calculated and the impact of the photons number and other parameters are studied. I considered approximation that mean numbers of photons are small in comparison to number of atoms. Small atomic squeezing is obtained under the approximation. One may obtain larger squeezing by increasing the mean number of photons. I plot-ted the graph for time evaluation of squeezing factor for different value of photons and fixed value of atoms presented in different atomic states.
