The Quantum Interference Of The Two Mode Cavity Field Spectrum

The influence of the interference effect on the spectra structure is discussed in detail in this thesis. In our work we choose the the binomial state as the incident field and we studied the quantum interference between the two mode spectrums through varifing the difference of the initial two mode frequencyΔ.In our work the cavity field spectra of a pair coupled two-level atoms interacting with two-mode radiation field is studied with the fields both in the binomial state. It's found that when g <Δ≤6g (g is the coupling coefficient between the atom and the field) the interference effect of the spectra can be ignored, whenΔis smaller than g the interference effect should be considered.Following we studied the cavity field spectra of a pair coupled two-level atoms in an ideal cavity interacting with two-mode radiation field is studied with the fields both in the binomial state. The result shows when the difference of the initial two mode frequencyΔis larger than 6g the interference effect of the spectra can be ignored, whenΔis smaller than 6g the interference effect should be considered .Especially whenΔis reduced gradually from 1.4g the three peaks of the mode I and mode II begin super positioning, the interference effect is obvious.At last we invested the quantum interference effect of the two mode spectrum in Kerr medium. The ruslt shows the Kerr medium have obviously repression affecting for the quantum interference effect of the two mode spectrum.The reason is the peaks of spectrum become weaker for the exsistence of the Kerr medium. WhenΔreduced to 0.5g the interference effect starts obvious.In our studing we foud although the atom molde is different the quantum interference between the two mode spectrums should not be ignored when the radiation field is binomial state.
