Atomic defects leave telltale optical fingerprints in quantum material
The tiny atomic defects so important for future quantum technologies can be difficult to spot. Fortunately, they leave behind some clues. The defects can alter how a material responds to light, producing a distinctive optical fingerprint that scientists can measure. The challenge is figuring out which fingerprints belong to which defects.Quantum Physics NewsRead More
Quantum interference keeps two atoms bound despite enough energy to break apart
How can something remain intact when it should naturally break apart? This question has been addressed by researchers at RPTU. Their work has led to the experimental observation of an unusual quantum state in which two atoms remain bound together even though they possess enough energy to separate. The results have been published in the
The fastest levitated spinning magnet ever made might help physicists search for dark matter
Tiny levitated magnets are able to avoid contact friction, making them useful for detecting extremely weak forces and magnetic fields and acting as ultralow-noise quantum sensors and precision measurement tools. Combining levitation with extreme cold further reduces unwanted motion that can make faint signals hard to detect.Quantum Physics NewsRead More
