Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how ...

Physicists have taken a first step in understanding quantum emergence -- the transition from 'one-to-many' particles -- by studying not one, not many, but two isolated, interacting particles. The ...

Investigating mysterious data in ultracold gases of rubidium atoms, scientists at the Joint Quantum Institute of the National Institute of Standards and Technology (NIST) and the University of ...

The synergism between atomic clusters (ACs)/nanoparticles (NPs) and single atoms has recently become a research focus. However, previous works often focus on the simple interaction between pure NPs ...

Ultrashort pulse interactions with atoms and materials encompass the study of electromagnetic pulses with durations on the femtosecond to attosecond scale, which provide an unparalleled window into ...

A team of physicists has created a cloud of ultracold atoms that stubbornly resists the most basic rule of everyday experience: when you pump energy into something, it heats up. Instead, this quantum ...
