Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity.

In quantum mechanics, particles do not behave like everyday objects. Instead of existing in one clearly defined state, they ...

Over the last few years, optical atomic clocks have broken record after record in precision timekeeping. Atoms are cooled to ...

The cosmological constant has been a problem in physics since Einstein, but new research may show why it takes the value that ...

A quantum spin liquid is a phase of matter in which the magnetic moments in a material do not align or freeze, even at ...

Physicists are preparing to test whether atomic clocks can experience quantum superposition, ticking faster and slower simultaneously. The concept merges principles from quantum mechanics and ...

Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: ...

The Casimir effect, a striking manifestation of quantum fluctuations, arises from the zero‐point energy inherent in the electromagnetic field. Predicted originally by Hendrik Casimir, this phenomenon ...

A tiny silica bead, just 100 nanometers across, sits suspended in a vacuum and vibrates under the grip of laser light. Those ...

Quantum mechanics would allow the Universe to eventually tunnel to the lowest energy state, or the ‘true’ vacuum, and that process would result in a cataclysmic global event. (CREDIT: Professor Zlatko ...

Theoretical and experimental work described in Nature Physics expands the repertoire of exotic phases of matter.

A single nanoparticle made of glass (a white point near the center of the photo) is confined in an optical potential created with a focused laser beam. By detecting the light scattered by the ...
