The effect of gravitational spin-orbit coupling on the circular photon orbit in the Schwarzschild geometry
Zhi-Yong Wang, Cai-Dong Xiong, Qi Qiu +2
The (1, 0)+(0, 1) representation of the group SL(2, C) provides a six-component spinor equivalent to the electromagnetic field tensor. By means of the (1, 0)+(0, 1) description, on…
Comment on "Uncertainty Relation for Photons"
Zhi-Yong Wang, Cai-Dong Xiong, Qi Qiu
In a recent interesting Letter [Phys. Rev. Lett. 108, 140401 (2012)] I. Bialynicki-Birula and his coauthor have derived the uncertainty relation for the photons in three dimensions…
Time operator in QFT with Virasoro constraints
Zhi-Yong Wang, Qi Qiu, Cai-Dong Xiong
Time operator is studied on the basis of field quantization, where the difficulty stemming from Pauli's theorem is circumvented by borrowing ideas from the covariant quantization o…
Photonic zitterbewegung and its interpretation
Zhi-Yong Wang, Cai-Dong Xiong, Qi Qiu
In term of the volume-integrated Poynting vector, we present a quantum field-theory investigation on the zitterbewegung (ZB) of photons, and show that this ZB occurs only in the pr…
Zitterbewegung and its significance for the Hawking radiation
Zhi-Yong Wang, Cai-Dong Xiong, Qi Qiu
The Hawking radiation can be viewed from very different perspectives, not all of which can be proved to be rigorously equivalent to one another. On the other hand, an old interest…
Average and instantaneous velocities of energy of evanescent modes
Zhi-Yong Wang, Wen-Chao Wang, Qi Qiu +2
Many theoretical and experimental investigations have presented a conclusion that evanescent electromagnetic modes can superluminally propagate. However, in this paper, we show tha…
