This paper has studied atomic evolution and manipulation of two-level atoms in a high-Q micro-cavity

and has specially studied atomic evolution after introducing a π pulse for the first atom.It is shown that

the π pulse leads not only to the reverse of atomic evolution

but it also leads to the recurrence of the first atom evolution in the evolution of the second atom.Therefore

this shows an effective way to manipulate the atomic evolution

and quantum information transfer.We have also proposed a ...
