Measuring tiny forces with atomic clouds For projects such as detecting gravity waves, physicists need to measure tiny forces precisely. Schreppler et al. developed an extremely sensitive method for force measurement. They applied a known force on a cloud of ultracold rubidium atoms in an optical cavity. The force caused the atoms to oscillate, and the researchers used optical measurements to monitor the motion. Under optimal conditions, the authors could measure forces with a level of…
