KW - trapped ion, entanglement sudden death, concurrence.
AB - <p style="text-align: justify;">We have studied the model for interaction of two trapped ions in a trap with 
a laser beam in the intermediate excitation regime. By applying unitary 
transformations, the system can be transformed into the Tavis-Cummings model. 
The entanglement dynamics of two trapped ions in this system has been investigated. 
With computation of the concurrence, unlike that in Tavis-Cummings model, 
we find that the entanglement of two ions in our model undergoes periodic death 
and revivals.</p>
