Squeezing and amplitude-squared squeezing effects on the dynamics of two   nonidentical two-level Squeezing and amplitude-squared squeezing effects on   the dynamics of two nonidentical two-level atoms atoms
  Squeezing and amplitude-squared squeezing for two two-level nonidentical atoms in lossless cavity has been investigated assuming the field to be initially in the coherent state. The time-dependent squeezing parameters has been calculated. The influence of the relative differences of two coupling constants on the squeezing parameters has been analyzed.
