Unusual sound waves discovered in quantum liquids
Ordinary sound waves—small oscillations of density—can propagate through all fluids, causing the molecules in the fluid to compress at regular intervals. Now physicists have theoretically shown that in one-dimensional ...
A phonon laser operating at an exceptional point
The basic quanta of light (photon) and sound (phonon) are bosonic particles that largely obey similar rules and are in general very good analogs of one another. Physicists have explored this analogy in recent experimental ...
Reversing cause and effect is no trouble for quantum computers
Watch a movie backwards and you'll likely get confused—but a quantum computer wouldn't. That's the conclusion of researcher Mile Gu at the Centre for Quantum Technologies (CQT) at the National University of Singapore and ...
A physics treasure hidden in a wallpaper pattern
An international team of scientists has discovered a new, exotic form of insulating material with a metallic surface that could enable more efficient electronics or even quantum computing. The researchers developed a new ...
Scientists answer long-held questions about relaxor ferroelectrics
The properties of a solid depend on the arrangement of its atoms, which form a periodic crystal structure. At the nanoscale, arrangements that break this periodic structure can drastically alter the behavior of the material, ...
CALET succeeds in direct measurements of cosmic ray electron spectrum up to 4.8 TeV
An international team of researchers extended their results from a previous study to directly measure the cosmic-ray all-electron (electron + positron) spectrum in an energy range from 11 GeV to 4.8 TeV with the Calorimetric ...
Researchers move closer to completely optical artificial neural network
Researchers have shown that it is possible to train artificial neural networks directly on an optical chip. The significant breakthrough demonstrates that an optical circuit can perform a critical function of an electronics-based ...
Electron microscope detector achieves record resolution
Electron microscopy has allowed scientists to see individual atoms, but even at that resolution not everything is clear.
Computer model predicts how fracturing metallic glass releases energy at the atomic level
Metallic glasses—alloys lacking the crystalline structure normally found in metals—are an exciting research target for tantalizing applications, including artificial joints and other medical implant devices. However, ...
