Exotic material exhibits an optical response in enormous disproportion to the stimulus

No earlier theory had envisioned that the responses would be so large! Scientists “poked” three crystals with pulses of light. Unexpectedly, the crystals exhibited the largest nonlinear optical response of any known crystal. The response was a huge amount of different colored light with twice the frequency of the pulse. These crystals are members of a new class of materials known as Weyl semimetals. …read more

Weird superconductor leads double life

Until about 50 years ago, all known superconductors were metals. This made sense, because metals have the largest number of loosely bound “carrier” electrons that are free to pair up and flow as electrical current with no resistance and 100 percent efficiency – the hallmark of superconductivity. …read more

Taming chaos: Calculating probability in complex systems

Daily weather patterns, brain activity on an EEG (electroencephalogram) and heartbeats on an EKG (electrocardiogram) each generate lines of complex data. To analyze this data, perhaps to predict a storm, seizure or heart attack, researchers must first divide up this continuous data into discrete pieces—a task that is difficult to perform simply and accurately. …read more

Beyond the WIMP: Unique crystals could expand the search for dark matter

A new particle detector design proposed at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) could greatly broaden the search for dark matter—which makes up 85 percent of the total mass of the universe yet we don’t know what it’s made of—into an unexplored realm. …read more

Researchers create microlaser that flies along hollow optical fiber

For the first time, researchers have optically trapped and propelled a particle-based laser for centimeters inside an optical fiber. The new flying microlaser enables highly sensitive temperature measurements along the length of the fiber and could offer a novel way to precisely deliver light to remote and inaccessible locations. …read more

New optical modules could improve thyroid cancer screening

Early diagnosis in thyroid cancer can improve a patient’s likelihood of recovery, but current screening methods use instruments with poor sensitivity and can yield inaccurate results. Consequently, doctors often have to rely on incomplete information to make diagnostic decisions and recommend treatments, and this can lead to patients receiving unnecessary surgeries or experiencing a reduced quality of life. …read more
