On the Quantum Mechanics for One Photon
Yapeng Hu, Weigang Qiu, Hongbao Zhang
This paper revisits the quantum mechanics for one photon from the modern viewpoint and by the geometrical method. Especially, besides the ordinary (rectangular) momentum representa…
Asymmetry of the electron spectrum in hole-doped and electron-doped cuprates
Huaiming Guo, Shiping Feng
Within the t-t'-J model, the asymmetry of the electron spectrum and quasiparticle dispersion in hole-doped and electron-doped cuprates is discussed. It is shown that the quasiparti…
Quantum secure direct communication network with Einstein-Podolsky-Rosen pairs
Fu-Guo Deng, Xi-Han Li, Chun-Yan Li +2
We discuss the four requirements for a real point-to-point quantum secure direct communication (QSDC) first, and then present two efficient QSDC network schemes with an N ordered E…
Improving the security of multiparty quantum secret sharing against Trojan horse attack
Fu-Guo Deng, Xi-Han Li, Hong-Yu Zhou +1
We analyzed the security of the multiparty quantum secret sharing (MQSS) protocol recently proposed by Zhang, Li and Man [Phys. Rev. A \textbf{71}, 044301 (2005)] and found that th…
The Community Structure of Econophysicist Collaboration Networks
Peng Zhang, Menghui Li, Jinshan Wu +2
This paper uses a database of collaboration recording between Econophysics Scientists to study the community structure of this collaboration network, which with a single type of ve…
Chaotic Turing Patterns displaying the beauty of chaos
Jinghua Xiao, Junzhong Yang, Gang Hu
The problem of Turing pattern formation has attracted much attention in nonlinear science as well as physics, chemistry and biology. So far all Turing patterns have been observed i…
