New Way to Edge Around a Difficult Quantum Physics Problem

Scientists have a new way to edge around a difficult problem in quantum physics, now that a research team from the National Institute of Standards and Technology (NIST) and University of Maryland's Joint Quantum Institute (JQI) have proved* their recent theory about how particles of light flow within a novel device they built.

Atomic-Scale Stress Test Using SLAC's X-Ray Laser

Scientists used the powerful X-ray laser at the U.S. Department of Energy's SLAC National Accelerator Laboratory to create movies detailing trillionths-of-a-second changes in the arrangement of copper atoms after an extreme shock. Movies like these will help researchers create new kinds of materials and test the strength of existing ones.

First Observation of Topological Effects for Light in Two Dimensions

Topology -- theunderstanding of how things are connected -- remains abstract, even with the popular example of doughnuts and coffee cups. This concept, esoteric as it appears, is also neat because it is the basis for creating ultrastable quantum "playgrounds." In topological systems, certain quantum behaviors can be carefully probed and even harnessed for all kinds of practical applications—from metrology to electronics.

Quantum Light Source Coaxed to Emit Ultrashort Burst of Light at a Desired Moment in Time

Usually, an elementary light source – such as an excited atom or molecule – emits light at an unpredictable instance in time. This spontaneous emission of light is a fundamental process within applications such as LEDs and lasers. However, for other applications it is desirable to receive single photons (light) at a specific moment with as little uncertainty as possible.
