Multiple mirrors magnify atom interferometry
From Physics World, October 20, 2022: A new multiple-mirror imaging technique could greatly improve the performance of atom interferometers, making them more useful in applications ranging from dark matter detection to quality control in manufacturing. The technique was developed by researchers at SLAC and a possible use for this would be in the Matter-wave Atomic Gradiometer Interferometric Sensor, a 100-metre-long atom interferometer currently being installed at Fermilab.
