Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In ...

In many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are ...

When quantum spins interact, they can produce collective behaviors that defy long-standing expectations. Researchers have now shown that the Kondo effect behaves very differently depending on spin ...

For the first time, researchers in China have accurately quantified how chaos increases in a quantum many-body system as it evolves over time. Combining experiments and theory, a team led by Yu-Chen ...

The article on causality in quantum theory reminds us that, until an observer takes a measurement, we are confronted by a fog of possible alternatives and that the measurement will cause these ...
