Putting a Spin on Light and Atoms

September 14, 2010

vapor-cell magnetometer Alkali-vapor magnetometers use light to put a spin on atoms and then measure that spin to detect magnetic fields. A team from Lawrence Berkeley National Laboratory, the University of California at Berkeley, and the Vavilov State Optical Institute in Russia have achieved a remarkable technical advance with this kind of magnetometer, with potential for improving atomic clocks, quantum memory devices, and a range of other scientific gadgets that depend on measuring spinning atoms with light.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
