The second-order correlation function includes the information of the quantum prop

Other experiments have separated the atomic paths using gratings [17.3] or a splitting due to a coherent transition between two internal states [17.4–6]. Laser cooling of the atoms may be employed to increase the de Broglie wavelength of the atoms [17.4, 7]. In

Effects of Land Degradation,ely US$70 per person per year. In addition to the decrease in land productivity, floods and droughts, increase in poverty and lowered food security are effects of land degradation. Increase in poverty tends to affect the health, education and standard of living of millions of people mainly in Asia and Africa.
