We give the quantum transform matrix, quantum dispersion relation and quantum transmissivity, and compare them with the classical dispersion relation ... More

Quantum theory of light double-slit diffractionMay 10 2013In this paper, we study the light double-slit diffraction experiment with quantum theory approach. Firstly, we calculate the light wave function in slits by quantum theory of photon. Secondly, we calculate the diffraction wave function with Kirchhoff's ... More

Full Quantum Theory of ${C_{60}}$ Double-slit DiffractionMay 10 2013In this paper, we apply the full new method of quantum theory to study the double-slit diffraction of ${C_{60}}$ molecules. We calculate the double-slit wave functions of ${C_{60}}$ molecules by Schr\"{o}dinger equation, and calculate the diffraction ... More

Can HI gas trace the matter density distribution linearly on large scales?Jan 09 2019It is customary to assume that HI gas traces the matter density distribution linearly on large scales. However, nonlinear effects which modulate HI gas in halos might spoil this. We employ three approaches to generate the mock HI density from an N-body ... More

Search for charged lepton flavor violation of vector mesons in BLMSSM modelOct 20 2017Oct 23 2017We analyze the charged lepton flavor violating (CLFV) decays of vector mesons $V\rightarrow l_i^{\pm}l_j^{\mp}$ with $V\in\{\phi, J/\Psi, \Upsilon, \rho^0, \omega \}$ in BLMSSM model. This new model is introduced as an supersymmetric extension of Standard ... More
