New quantum switch turns metals into insulators

Most modern electronic devices rely on tiny, finely-tuned electrical currents to process and store information. These currents dictate how fast our computers run, how regularly our pacemakers tick and how securely our money is stored in the bank. In a study published in Nature Physics, researchers at the University of British Columbia have demonstrated an … Read more New quantum switch turns metals into insulators

IoP physicists cool an atom-ion mixture to the quantum regime

Over the past years, physicists have developed techniques to create extremely cold atoms and ions. These ultra-cold particles have many uses; for example, they can be used as building blocks for quantum computers and highly precise clocks. Ideally, for such applications, one would also have mixtures of very cold atoms and ions at one’s disposal, … Read more IoP physicists cool an atom-ion mixture to the quantum regime

UChicago physicists discover hidden symmetries, opening new avenues for material design

When you knock on a melon to see if it’s ripe, you are using sound waves to probe the structure of the material inside. Physicists at the University of Chicago were using the same concept to explore how sound waves travel through patterned structures when they noticed an oddity: completely different structures sounded the same. … Read more UChicago physicists discover hidden symmetries, opening new avenues for material design

Groningen’s physicists have visualized hydrogen at the metal-to-metal hydride interface

University of Groningen physicists have visualized hydrogen at the titanium/titanium hydride interface using a transmission electron microscope. Using a new technique, they succeeded in visualizing both the metal and the hydrogen atoms in a single image, allowing them to test different theoretical models that describe the interface structure. The results were published on 31 January … Read more Groningen’s physicists have visualized hydrogen at the metal-to-metal hydride interface

A quantum of solid

It is well known that quantum properties of individual atoms can be controlled and manipulated by laser light. Even large clouds of hundreds of millions of atoms can be pushed into the quantum regime, giving rise to macroscopic quantum states of matter such as quantum gases or Bose-Einstein condensates, which nowadays are also widely used … Read more A quantum of solid

Current model for storing nuclear waste is incomplete

The materials the United States and other countries plan to use to store high-level nuclear waste will likely degrade faster than anyone previously knew because of the way those materials interact, new research shows. The findings, published today in the journal Nature Materials, show that corrosion of nuclear waste storage materials accelerates because of changes in … Read more Current model for storing nuclear waste is incomplete
