Magnetism is usually taught as a story of straight lines, with field arrows marching neatly from north to south. In a lab at Florida State University, that picture has just been shattered by a new ...

Redefining the repeating pattern in photonic crystals creates tightly confined pathways for light while preserving symmetry, offering a simple route to ultracompact and low loss light circuits.

Researchers have demonstrated a novel concept for exciting and probing coherent phonons in crystals of a transiently broken symmetry. The key of this concept lies in reducing the symmetry of a crystal ...
