The Energy-level Configuration of Jaynes-Cummings Model in An External Field

Fei Zeng

We study a atomic system coupled to a quantum field and an external classical field at the same time. The interaction betwere the atom and the external field is regarded as a perturbation. Using perturbation theory to solve the energy-level configuration of this quantum system, where the first-order are zero, and the second-order are proportionate to the second power of the coupling constant betwere the atom and the external field.

Study on the Energy Level Splitting of the Francium Atom Fr in an External Magnetic Field

Win Moe Thant

In This paper the normal Francium atom is considered with the use of non relativistic quantum mechanical approach and the Bohrs atomic model. We study the energy shift values of a Francium atom by the external magnetic fields effect we considered the two cases that effect without external magnetic fields and those of with the external magnetic fields.

Fisher information and quantum state estimation of two-coupled atoms in presence of two external magnetic fields

Hanaa Abu-Zinadah, S. Abdel‐Khalek

We consider a quantum system of an atom-atom interaction in the presence of two external magnetic and classical fields in x, and z directions. The dynamical behavior of single atom quantum quantifiers such as the atomic Wehrl entropy, atomic Fisher information and quantum entropy are investigated. The quantum entanglement degradation in regard to the atomic state estimation are discussed through the evolution of the atomic Fisher information flow, and the effects of the external classical fields and types of time dependent coupling between the two atoms are examined. We explore the relationship between different statistical quantities in the absence and presence of classical field during the time evolution. The results show that the creation and manipulation of entanglement by external fields greatly benefit within the suitable choice of the kind of time dependent coupling among the two atoms and external.
