Single-atom entropy squeezing and quantum entanglement in Tavis–Cummings model with atomic motion

Zou Yan

We examine the single-atom entropy squeezing and the atom–field entanglement in a system of two moving two-level atoms interacting with a single-mode coherent field in a lossless resonant cavity. Our numerical calculations indicate that the squeezing period, the squeezing time and the maximal squeezing can be controlled by appropriately choosing the atomic motion and the field-mode structure. The atomic motion leads to a periodical time evolution of entanglement between the two-atom and the field. Moreover, there exists corresponding relation between the time evolution properties of the atomic entropy squeezing and that of the entanglement between the two atoms and the field.

Squeezing Property of Binomial State Field under the Anti-Tavis-Cummings Model

Hong‐Guang Piao

The interaction between two identical two-level atoms and single-mode binomial light field is studied in anti-Tavis-Cummings model,and the atoms stay in entangled state initially.When the classical field is strong enough,the interaction between the atoms and the light field can turn into an effective anti-Tavis-Cummings model and Tavis-Cummings model under the condition of large detuning.In this paper,we mainly probe into the squeezing property of the binomial state in anti-Tavis-Cummings model,and the influence of initial field parameters on the squeezing property of the field are discussed.The results show that the degree and period of squeezing depend strongly on the initial parameters,and energy nonconservation item has a great impact on squeezing property.
