The world’s best clocks may be sensitive to an odd mix of quantum and relativistic effects that would stretch time and test ...

By using something called a quantum grid, scientists have found a clever way to simultaneously measure momentum and position ...

In their study, Zhao and Smalyukh created a space–time crystal in the nematic phase of a liquid crystal. In this phase the crystal’s rod-like molecules align parallel to each other and also flow like ...

Researchers find that a photon can spend a negative amount of time in an excited atomic state while passing through a cloud ...

Researchers in Vienna have discovered something remarkable: crystals that don’t form in space, like diamonds or salt, but in time itself. Instead of atoms arranging neatly into repeating patterns, ...

Seeking endorsements for her new book, Chanda Prescod-Weinstein finds herself staring at fundamental questions of space, time ...

The visible patterns produced by the time crystals could be used for data storage and anti-counterfeiting designs.

Amid high expectations for quantum technology, a new paper in Science reports a proven quantum advantage. In an experiment, ...

Physicists from Osaka Metropolitan University and the Korea Advanced Institute of Science and Technology were able to observe ...

Scientists in Japan have uncovered a strange new behavior in “heavy” electrons — particles that act as if they carry far more mass than usual. These electrons were found to be entangled, sharing a ...
