Researchers have defined what it means for time translation symmetry to be spontaneously broken in a quantum system, and show with analytical arguments and numerical simulations that this occurs in a ...

From snowflakes to quartz, nature’s crystalline structures form with a reliable, systemic symmetry. Researchers at Drexel University, who study the formation of crystalline materials, have shown that ...

In a surprising twist, researchers have identified crystals that are symmetrical but nevertheless absorb light as if they were chiral (Science 2025, DOI: 10.1126/science.adr5478). The discovery ...

A time crystal is, essentially, an object that appears to have movement while remaining at its lowest energy state (ground state). When theoretical physicist and Nobel laureate Frank Wilczek ...

The light-matter interaction has long been one of the most advanced areas in physics. Recently, it has attracted more attentions due to the rapid development of ultra-short lasers, and a variety of ...

Forget solid, liquid, and gas: there are in fact more than 500 phases of matter. In a major new article scientists reveal a modern reclassification of all of them. Forget solid, liquid, and gas: there ...

Nature keeps a few secrets. While plenty of structures with low symmetry are found in nature, scientists have been confined to high-symmetry designs when synthesizing colloidal crystals, a valuable ...

Traditional crystals are composed of extremely orderly, symmetrically arranged repeating patterns of atoms that don’t move. Recently, however, a team of physicists has proposed a type of crystal that ...

From snowflakes to quartz, nature's crystalline structures form with a reliable, systemic symmetry. Researchers who study the formation of crystalline materials have shown that it's now possible to ...
