Controlling the quantum world: the science of atoms, by National Research Council, Division on Engineering and

By National Research Council, Division on Engineering and Physical Sciences, Board on Physics and Astronomy, Committee on AMO 2010

As a part of the Physics 2010 decadal survey undertaking, the dept of power and the nationwide technology beginning asked that the nationwide learn Council examine the possibilities, over approximately the following decade, in atomic, molecular, and optical (AMO) technological know-how and expertise. particularly, the nationwide study Council was once requested to hide the nation of AMO technology, emphasizing fresh accomplishments and settling on new and compelling clinical questions. Controlling the Quantum World, discusses either the jobs and demanding situations for AMO technology in instrumentation; clinical study close to absolute 0; improvement of tremendous severe x-ray and laser resources; exploration and regulate of molecular strategies; photonics on the nanoscale point; and improvement of quantum info expertise. This booklet additionally deals an evaluate of and suggestions approximately serious concerns touching on retaining U.S. management in AMO technology and technology.

Example text

For such optically pumped, hyperpolarized atomic gases, the signal per nucleus is about 100,000 times larger than the signal per nucleus in normal MRi. this more than makes up for the smaller density of the nuclei in these gases compared with the density in human tissue. 1 percent. Using a single electron held in a magnetic trap, this tiny modiication has been measured to astonishing accuracy: 10 decimal places. equally astonishing, the theory of these radiative corrections has been used to calculate the effect to the same precision.

The state-of-the-art accuracy of atomic clocks, which is approaching one second in 60 million years, involves the use of a small number of neutral atoms or a single ion in electric traps. Such accuracies are not merely academic—as indicated above, they are necessary for increasing the precision of navigation, from applications in space exploration to advanced architectures in GPS. to attain such accuracy, the atoms in atomic clocks must be isolated from their environment, including from other nearby atoms.

In such a gas, all of a macroscopic fraction of the particles can simultaneously occupy the lowestenergy “wave” in the box in which the atoms are kept. Ultracold gases offer the intriguing possibility of building completely controllable models for matter. they can be conined in a variety of geometries, including situations that are effectively one- or two-dimensional rather than threedimensional. it is also possible to conine them in ways that mimic the periodic structure in solid crystals. these uses of ultracold atoms as quantum simulators are among the most exciting recent developments in AMo science.
