Sea Water-The Source of Solutions of Modern-Day Water and Other crucial Crisis
Water scarcity is the most crucial problem around the Globe. It is because of two converging phenomena: Growing of fresh water use and Depletion of usable freshwater resources. The Millennium Development Goals within the United Nations, Millennium Declaration stated that by 2015 they resolve to “halve the proportion of people who are unable to reach or to afford safe drinking water”. In this case the seawater can be the source of the crucially needed “Drinking water” but still it has to be purified for that. For this matter , an idea can be presented for making not only drinking water but also producing H2 and O2 gas
Quantum Analysis of sub harmonic generation with two-mode coherent light
Theoretical Physics Letters (IF 1.4) : PTL Coresearch
Under this paper, the statistical and squeezing properties of light-driven by sub-harmonic generation with two-mode coherent light are studied. With interaction Hamiltonian of both two-mode coherent and sub harmonic generation, we have drive master equation of system under consideration. From the master equation, the solution of the C-number Langavine equation is derived. It helps us to solve quadrature variance, quadrature squeezing, mean, and variance of photon number for light produced by sub-harmonic generation with the two-mode coherent light state. And the result shows that; the squeezing occurs in plus quadrature with the maximum squeezing of 87% for
γ=1 and k=0.3. The photon statistics of the system under consideration is subpoissonian in which both mean & variance are increasing as kappa increase.
