From insulator to conductor in a flash

In recent decades, computers have become faster and hard disks and storage chips have reached enormous capacities. But this trend cannot continue forever. Physical limits are preventing silicon-based computer technology from ...

The synchronized dance of skyrmion spins

In recent years, excitement has swirled around a type of quasi-particle called a skyrmion that arises as a collective behavior of a group of electrons. Because they're stable, only a few nanometers in size, and need just ...

Researchers make breakthrough in high-pressure magnetic detection

According to a study published in Nature Materials, a collaborative research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences (CAS) and the University of Science and Technology of China ...

Towards quantum simulation of false vacuum decay

Phase transitions are everywhere, ranging from water boiling to snowflakes melting, and from magnetic transitions in solids to cosmological phase transitions in the early universe. Particularly intriguing are quantum phase ...

Seeing how grain boundaries transform in a metal

Grain boundaries are one of the most prominent defects in engineering materials separating different crystallites, which determine their strength, corrosion resistance and failure. Typically, these interfaces are regarded ...
