| Abstract: | The fidelities of quantum states in the two-atom Tavis-Cummings model where the atoms are driven by an external classical field are derived. The influence of the external field and the dipole-dipole interaction of the atoms in a special initial state on the fidelity is discussd. |

| Keywords: | fidelity Tavis-Cummings model external classical field |
