The entropy squeezing properties in a system of single-mode field interacting with coupled atoms
单模辐射场与耦合双原子相互作用系统中场熵的压缩特性

The field entropy squeezing properties in a system of vacuum field interacting with coupled two atoms are studied by means of quantum theory,and we focus our attention on the discussion of the influence of the initial state of atoms and the coupling strength on the field entropy squeezing.The results obtained using the numerical method indicate that the field entropy can be squeezed periodically if the atoms are initially in a suitable coherent superposition of the exited state and the ground state,and the dipole interaction between atoms has an important influence on the field entropy squeezing.
