X-ray four-wave mixing captures elusive electron interactions inside atoms and molecules

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

Metal clumps in a quantum state: Physicists place thousands of sodium atoms in a 'Schrödinger's cat state'

Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, ...

Scientists just overturned a 100-year-old rule of chemistry, and the results are “impossible”

Chemists at UCLA are showing that some of organic chemistry’s most famous “rules” aren’t as unbreakable as once thought. By creating bizarre, cage-shaped molecules with warped double bonds—structures ...

A year after undermining Bredt’s rule, UCLA scientists have made cage-shaped, double-bonded molecules that defy expectations

Chemical bonds are forces that hold atoms together in molecules through shared electrons. The rules governing bonding and the shapes of molecules are often thought to be absolute. Geometries of double ...

Cutting-Edge Physics and Chemistry Unfold One Quintillionth of a Second at a Time

Just about anybody who played hide-and-seek as a kid remembers counting, with eyes (presumably) covered, in units of one-one-thousand. “One-one-thousand. Two-one-thousand. Three-one-thousand.” It’s ...
