Physicists are learning to treat light not as an untouchable beam that simply passes through matter, but as something that ...

The universe is generally believed to be expanding at an accelerating rate, thanks to a mysterious force dubbed dark energy. But how exactly does this force work? Researchers in the UK have conducted ...

Ultracold atoms have successfully mimicked a fundamental quantum effect normally found in electronic circuits.

Yuri Ralchenko led one of the oldest teams at the National Institute of Standards and Technology. The fate of some experiments hangs in the air. Lost Science Yuri Ralchenko led one of the oldest teams ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of ...

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies required. The authors of a new, non-peer reviewed study detail how the a ...

While many Earth-based experiments have been run to try to detect dark matter, the mysterious substance remains elusive. Now physicists have proposed a new experiment that would try to find signals by ...

Why do atomic nuclei, which should easily break apart, form more readily in extreme environments? This cosmic mystery, which ...

The University of Wisconsin’s physics department was recognized for its experimentation and creation of one of the most highly-efficient atomic clocks ever. The optical lattice atomic clock is behind ...

THIS little handbook, evidently the outcome of long experience in teaching young students, is primarily intended for science masters in secondary schools. It includes a well-selected and well-arranged ...

A team has succeeded in computing how atomic nuclei of the Calcium element behave in collisions with electrons. Results agree very well with available experimental data. For the first time, a ...

Atomic clocks. They almost sound like something out of science fiction, or an experiment confined to some elite physics lab, but in reality, they’ve been around since the 1950s in one form or another.
