    "abstract": "A scheme for generating the maximally entangled mixed state of two atoms\non-resonance asymmetrically coupled to a single mode optical cavity field is\npresented. The part frontier of both maximally entangled mixed states and\nmaximal Bell violating mixed states can be approximately reached by the\nevolving reduced density matrix of two atoms if the ratio of coupling strengths\nof two atoms is appropriately controlled. It is also shown that exchange\nsymmetry of global maximal concurrence is broken if and only if coupling\nstrength ratio lies between $\\frac{\\sqrt{3}}{3}$ and $\\sqrt{3}$ for the case of\none-particle excitation and asymmetric coupling, while this partial\nsymmetry-breaking can not be verified by detecting maximal Bell violation.",
