A key role of transversality condition in quantization of photon orbital angular momentum
Chun-Fang Li
The effect of the transversality condition on the quantization of the photon orbital angular momentum is studied. The quantum gauge that is deduced from the transversality conditio…

Degree of diffraction for monochromatic light beams
Jie Wu, Shuang-Yan Yang, Chun-Fang Li
A parameter, called the degree of diffraction, is defined to describe the diffractive spreading of a monochromatic light beam. The same as the degree of paraxiality that was introd…

On angular momentum of photons: the role of transversality condition in quantum mechanics
Chun-Fang Li
Whether the total angular momentum of the photon can be separated into spin and orbital parts has been a long-standing problem due to the constraint of transversality condition on…
