Photon exchange

Methods for two distant parties to exchange their secret messages using single photons are considered. There existed several such methods but they are either insecure or face with information leakage problem. In this paper a new method to overcome the above-said limitations is proposed. The proposed method is also efficient because it also uses single photons in two degrees of freedom.

The results indicate that the effect of vector unparticles is larger than its scalar all over the range of collision energy, as much greater than Higgs (h) and radion (φ) in the low energy. Z boson exchange also contributes the greatest to the process in both unpolarized and polarized conditions in higher energy regions when compared to photon exchange (γ) which normally dominates at the lower energies.

Despite the prediction of the Higgs boson at Large Hadron Collider (LHC) in the CERN in 2012 after it has been theorized for over 50 years, however, the Standard model (SM) still can not explain the mass of neutrinos; the hierarchy problem; the contribution of dark energy, dark matter and CP violation in cosmology.

This paper study the coherent Stokes generation in a transient stimulated Raman scattering regime by Hydrogen gas-filled hollow-core photonic crystal fibres configuration. The temporal and spatial evolution of the pump and Stokes field envelopes as well as the coherence and population inversion are numerically calculated. The Stokes generation efficiency and the influence of pump pulse width and gas pressure on the energy exchange along fibre are investigated.

Dark matter (DM) is a special matter kind. The total amount of dark matter should be around five times bigger than that of ordinary matter. Currently, there are many dark matter models, such as the Cold Dark Matter model with a cosmological constant (ΛCDM) [1] and the vector-fermion dark matter model.

The change in other two fermion processes is called Bhabha process. In this paper, we discuss the Bhabha process in the Randall –Sundrum (RS). We caculated the cross section for photon  , boson Z, radion  and Higgs h exchange and evaluated exchange contributions of the Bhabha process in detail.

The use of Jatropha (Jatropha curcas L.) as a source of biofuel is documented. The physiological characteristics and growth studies of Jatropha have received less attention. In the present study, we measured leaf gas exchange with an infrared gas analyzer for red (immature) and green (mature) leaves of Jatropha curcas in response to various environmental conditions including photosynthetic photon flux density (PPFD), vapor pressure difference, and temperature.
