A time crystal is a form of matter that shows continuous, repeating patterns over time, much like how atoms in a normal ...

Molecular crystals have emerged as a captivating class of materials that blend the intrinsic order of crystalline solids with the dynamic responsiveness typically associated with soft matter. Their ...

Ice crystals are surprisingly tolerant of defects in their structure. The findings come from the first-ever molecular-resolution observations of nanoscale samples of ice frozen from liquid water.

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 ...

Optical microscope image of a representative crystal that possesses centrosymmetry, yet shows differential absorption of circularly polarized light. The crystal is made of lithium, cobalt, selenium ...

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, ...
