Physicists have proposed a way to extract the internal quantum states of electron wave packets by analyzing how those packets scatter off atoms. The approach, grounded in theoretical derivations ...

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has been pushed even further. For the first time, researchers have observed ...

Scientists at the University of Konstanz in Germany have advanced ultrafast electron microscopy to unprecedented time resolution. Reporting in Science Advances, the research team presents a method for ...
