From a combination of Maxwell’s electromagnetism with Planck’s law and the de Broglie hypothesis, we arrive at quantized photonic wave groups whose constant phase velocity is equal to the speed of light c = ω/k and...

With propagating through a dispersive medium,the temporal–spectral profile of optical pulses should be inevitably modified.Although such dispersion effect has been well studied in classical optics,its effect on a sin...

Two coupled paralnetric four-wave-mixing processes in Rb atoms are studied using perturbation theory, which reveals clear evidence of tile appearance of quantum beat at 608cm^-1, corresponding to the energy difference...
