A strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating ...

Time crystals, a collection of particles that "tick"—or move back and forth in repeating cycles—were first theorized and then ...

A cluster of 7,000 sodium atoms has just been coaxed into behaving as a single, ghostly wave, stretching quantum weirdness ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

"Suppose you knew everything there was to know about a water molecule — the chemical formula, the bond angle, etc.,” says Joseph Thywissen, a professor in the Department of Physics and a member of the ...

The ability to tune the interactions between atoms in a Bose-Einstein condensate has led to atomic wave packets that can propagate without dispersion and other novel quantum states. One of the ...

Magnetised plasma dynamics and wave interactions constitute a pivotal research area that bridges fundamental physics and practical applications ranging from fusion energy to space and astrophysical ...

A team from Nagoya University in Japan has observed, for the first time, the energy transferring from resonant electrons to whistler-mode waves in space. Their findings offer direct evidence of ...

Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely ...
