Emission spectra of a pair of two-level atoms interacting with a quantized optical field in an ideal cavity

Weifeng Wang, Xueji Xu

This article investigates the interaction of a pair of two-level atoms with a quantized radiation field in an ideal cavity, taking into account the dipole-dipole interaction between the two atoms. One-photon and two-photon transitions are treated. It is found that the spectra have eight completely asymmetric peaks in both cases. For an intense field in both processes, a striking feature with five asymmetrically distributed peaks is recorded if ga γ where ga is the dipole-dipole coupling constant and γ is the detector's width. If the atoms' coupling is weak and the spectrometer's resolution is low, say ga < γ, then only a three-peak structure can be obtained.

Dynamics for two atoms interacting with intensity-dependent two-mode quantized cavity fields in the ladder configuration

Sudha Singh, C. H. Raymond Ooi, Amrita Amrita

Exact solutions are obtained for a collective model of two identical two-level atoms interacting with a quantized bimodal field with intensity-dependent coupling terms in a lossless cavity. A unitary transformation method is used to solve the time-dependent problem that also gives the eigensolutions of the interaction Hamiltonian. The atomic population dynamics and the dynamics of the photon statistics of the two cavity modes are studied. We present evidence of cooperative effects.
