Physicists shed new light on unanswered questions about glass-liquid transition

Glasses are peculiar materials exhibiting excellent and well-known properties, but also some phenomena that are still not fully understood, even though they have been studied for more than a century. In particular, researchers have not yet reached a complete description of the glass formation process, upon cooling a liquid, and the converse transition of glass to a more stable state—called supercooled liquid—when it is heated up.
