Despite cold weather and cloudy skies, UMD's annual Maryland Day (April 25, 2015) attracted thousands of visitors eager to learn about the university. The JQI was again located on the lawn outside the Physics Building, and provided fun examples and analogs of quantum topics with demonstrations of parametric down conversion, wave-particle duality, charged dust traps, and the Meissner effect. The JQI thanks ...

In another advance at the far frontiers of timekeeping by National Institute of Standards and Technology (NIST) researchers, the latest modification of a record-setting strontium atomic clock has achieved precision and stability levels that now mean the clock would neither gain nor lose one second in some 15 billion years*—roughly the age of the universe. Precision timekeeping ...

The word “defect” doesn’t usually have a good connotation--often indicating failure. But for physicists, one common defect known as a nitrogen-vacancy center (NV center) has applications in both quantum information processing and ultra-sensitive magnetometry, the measurement of exceedingly faint magnetic fields. In an experiment, recently published in Science, JQI Fellow Vladimir Manucharyan and colleagues at Harvard University used NV ...

The OSA announced JQI Fellow and NIST scientist Paul Julienne as the 2015 William F. Meggers Award recipient. The William F. Meggers Award recognizes outstanding work in spectroscopy. According to the citation, Julienne is being recognized for "seminal contributions to precision photoassociation and magnetic-Feshbach spectroscopy of ultracold atoms, and the application of these techniques to the formation of cold polar ...
