Light-pulse atom interferometry enables precision tests of gravity, electrodynamics and quantum mechanics, as well as practical applications in inertial navigation, geodesy, and timekeeping. In our 10-meter atomic fountain, designed for a precision test of the weak equivalence principle, we have demonstrated an acceleration sensitivity of 6.7 x 10^{-12} g, the ...
Critical, imminent changes in the world energy portfolio have amplified pressure on development of advanced energy storage technology, for the grid, automotive and consumer electronics sectors. Technology advances are not only required to enable the largest entry of people to the middle classes in human history, but also to avert ...
