A simple twist unlocks never-before-seen quantum behavior

Twisted materials — known as moiré structures — have revolutionized modern physics, emerging as today’s “alchemy” by creating entirely new phases of matter through simple geometric manipulation. The term “moiré” may sound familiar — it describes the strange rippling patterns you sometimes see when photographing striped shirts or screens; in physics, the same underlying principle…

First-of-its-kind crystal laser could power safer sensors and smarter tech

In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported a photopumped lasing from a buried dielectric photonic-crystal surface-emitting laser emitting at room temperature and an eye-safe wavelength. Their findings, published in IEEE Photonics Journal, improve upon current laser design and open new avenues…
