Maximally entangled mixed states of two atoms trapped inside an optical   cavity
  In some off-resonant cases, the reduced density matrix of two atoms symmetrically coupled with an optical cavity can very approximately approach to maximally entangled mixed states or maximal Bell violation mixed states in their evolution. The influence of phase decoherence on the generation of maximally entangled mixed state is also discussed.   PACS numbers: 03.67.-a, 03.65.Ud
