    "abstract": "In this paper we consider a system of two two-level atoms interacting with a\nsingle-mode quantized electromagnetic field in a lossless resonant cavity via\n$l$-photon-transition mechanism. The field and the atoms are initially prepared\nin the coherent state and the excited atomic states, respectively. For this\nsystem we investigate the entropy squeezing, the atomic variances, the von\nNeumann entropy and the atomic inversions for the single-atom case. We show\nthat the more the number of the parties in the system the less the amounts of\nthe nonclassical effects exhibited in the entropy squeezing.\n  The entropy squeezing can give information on the corresponding von Neumann\nentropy. Also the nonclassical effects obtained form the asymmetric atoms are\ngreater than those obtained form the symmetric atoms. Finally, the entropy\nsqueezing gives better information than the atomic variances only for the\nasymmetric atoms.",
