Ramsey resonance of coherent population trapping in slow rubidium beam

I. M. Sokolov

We calculate the coherent population trapping (CPT) resonance in slow beam of rubidium 87 atoms caused by of their interaction with bichromatic electromagnetic field in two separated spatial domains. In the case of monovelocity beam we study the properties of the CPT resonance depending on type of working transitions, velocity of the atomic beam, intensity and polarization of electromagnetic fields, and space separation in Ramsey scheme.

“Macroscopic” quantum superpositions: Atom-field entangled and steady states by two-photon processes

Moorad Alexanian, Subir K. Bose

The dynamics of an exact two-photon Hamiltonian is used to study the time evolution of an initially disentangled pure state of the atom-field system as it goes through cycles of entanglement separated by instances of disentanglement. For specific initial states of the electromagnetic field, the output state is a pure quantum superposition of a squeezed vacuum state and an orthogonal, odd-photon-number state. The odd-photon-number state, which is not a squeezed state, exhibits both nonclassical sub-Poissonian and classical super-Poissonian photon statistics. In the latter case the quantum superposition resembles a macroscopic superposition state. Conditions are obtained on the atom-cavity interaction time for such states to represent the steady states in the injection in a high-$Q$ cavity of a monoenergetic, low-density beam of three-level atoms in a coherent state.

Quantum Coherence of Interaction Between Two-level Atom and Electromagnetic Field

Zhihong Wang

Quantum coherence of two-level atom in a certain circumstance is discused by the method of density matrix.Hamitonian operator of two-level atom in classic electromagnetic field is expressed by atomic operators;based on Schdinger equation,the evolution equations of density matrix in two-level atomic system is gained;by solving the evolution equations,the detailed density matrix in such a system is derived.It is obtained that the pure state system can retain nicer quantum coherence.
