  1. By calculating the feynman diagram in rtf, we find that when taking into account both the thermal photon emission, absorption and the virtual photon exchange processes, the infrared divergences at zero and finite temperature can be cancelled at the same time. the full quantum calculation results for soft photon radiation coincide completely with the poisson distribution obtained in the semiclassical approximation ( the coupling of the classical current and quantized field )

    通過實時溫度場論下的費曼圖計算，我們得到：將實光子的發射、吸收，虛光子的交換過程同時考慮時，零溫場論中出現的和由溫度效應引起的紅外發散都能得到消除；並且完全量子場論下的軟光子輻射幾率與半經典近似下（經典的電流和量子化的電磁場之間的耦合）得到的泊松分佈結果完全一致。
  2. Through studying the interaction between a two - level atom and a single mode emission field in rotating - wave approximations of jaynes - cummings model, the atom and the field are in a coupled superposition state - entangled state. the expectation value of atom dipole moment is always zero, but the fluctuation of dipole moment is a non - zero constant

    通過對旋波近似下j - c模型中的二能級原子和單模場相互作用體系的研究，得到激發態原子可演化為場和原子的耦合疊加態- - -糾纏態。
