A time crystal is a form of matter that shows continuous, repeating patterns over time, much like how atoms in a normal crystal repeat in space. Examples once existed in only complex, quantum matter, ...

Imagine a clock that doesn’t have electricity, but its hands and gears spin on their own for all eternity. In a new study, physicists at CU Boulder have used liquid crystals, the same materials that ...

In a groundbreaking scientific achievement, researchers have successfully created a new phase of matter known as time crystals, which fascinatingly exhibit behaviors akin to perpetual motion. We will ...

Researchers have developed a blueprint for weaving hopfions—complex, knot-like light structures—into repeating spacetime crystals. By exploiting two-color beams, they can generate ordered chains and ...

Here’s what you’ll learn when you read this story: First theorized in 2012, time crystals are similar to normal crystals, but instead of their lattice of atoms repeating in a physical 3D space, they ...
