A University of Toronto experiment showing that photons can spend a negative amount of time inside a cloud of atoms has been ...

Why do certain surfaces behave very differently from what theoretical calculations suggest? Scientists long assumed that the ...

No time travel involved.

Researchers have discovered that atoms can be mixed, separated, and recombined within the same experiment, providing a ...

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 ...

Scientists long assumed that the aluminum oxide surface should be highly reactive and capable of splitting water molecules.

Using one of the world's most precise atomic clocks, physicists have shown that time runs a tiny bit slower if you change your height above the Earth's surface by a minuscule 0.008 inch (0.2 ...

Dark matter doesn’t absorb or emit light. It also doesn't interact with ordinary matter, making it hard to detect. Yet, a new theoretical study shows that hypothetical dark matter particles could ...

Cold atom experiments trap atoms to probe quantum effects, enabling ultra-precise sensing, timekeeping, and monitoring of Earth and space phenomena. (Nanowerk News) Cold atom experiments are among the ...

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 ...
