Study discovers pairing of electrons in artificial atoms, a quantum state predicted more than 50 years ago
3D view of some of the structures built atom-by-atom from silver (small hillocks). A rectangular and a circular electron cage are seen in the top left quarter of the image.…
Visualizing the microscopic phases of magic-angle twisted bilayer graphene
Scanning tunneling microscopy images of twisted bilayer graphene, which show the graphene atomic lattice (left panel) and the magic-angle graphene moiré superlattice (right panel). Credit: Kevin Nuckolls, Yazdani Group, Princeton…
Switching ‘spin’ on and off (and up and down) in quantum materials at room temperature
Illustration of electron spin in a quantum material. Credit: Sebastian Gorgon Researchers have found a way to control the interaction of light and quantum ‘spin’ in organic semiconductors, that works…
Researchers develop a unique quantum mechanical approach to determining metal ductility
The team found that higher (increased) charge activity is responsible for improved ductility in body-centered cubic metals. The yellow region, which represents the higher electronic charge in the interstitials (area…
Study demonstrates many-body chemical reactions in a quantum degenerate gas
Images of atomic and molecule Bose-Einstein condensates. Panel (a) shows the image of an atomic Bose-Einstein condensate of 60,000 cesium atoms at the temperature 10 nano-Kelvins. False colors are used…
A quantum leap in mechanical oscillator technology

Bigger and better quantum computers are possible with new ion trap dubbed the Enchilada
Electrical engineer Ray Haltli optimizes parameters before placing gold wire bonds on an ion trap. When ready, the machine runs automatically, placing up to seven wires per second. Credit: Craig…
Research team demonstrates a new ‘primary standard’ for measuring ultralow pressures
To verify the accuracy of their new approach for measuring ultra-low vacuum pressures, NIST researchers built a high-performance version of a traditional pressure metrology setup, known as a dynamic expansion…
