| Abstract: | The entropy evolution of a pair of atoms interacting with a single-mode vacuum field is investigated by using the quantum reduced entropy,and the influence of the atomic dipole-dipole interaction on the field entropy evolution is discussed.The result indicates that the increase of the coupling leads to the decrease of the field entropy. |
| Keywords: | a pair of atoms single-mode vacuum field reduced entropy quantum entanglement field entropy evolution |
