RAMAN INTERACTION OF A PAIR OF TWO-LEVEL ATOMS WITH A RADIATION FIELD

LUO ZHEN-FET, XU ZHI-ZHAN, Xu Lei +1 more

The Raman interaction of a pair of two-level atoms with the radiation field is studied. The emission spectra for two interacting processes are calculated in which either two atoms couple to the field with different constants or with the same constant but at the same time the dipole-dipole interaction between two atoms being included in the consideration. The effect of the relative value of two atom-field coupling constants and also that of atomic dipole-dipo-le interaction on the emission spectra are analyzed.

Decoherence Properties of a Two-level Atom Interacting with aThermal Radiation Field without Rotating Wave Approximation

Deng-Yu Zhang

The interaction of a two-level atom with a thermal radiation field for single-photon processes and two-photon processes without rotating wave approximation is analysed. The atom's reduced density matrix is calculated when the quantum theory in small system coupled to thermal reservoir is used. The decoherence properties of atom is analyzed.[WT5HZ]
