Chemists capture light-matter hybrid particles traveling long distances

Phys · · 1041 words · By Maureen Searcy

Researchers at the University of Chicago have developed an ultrafast imaging method using time-resolved photoemission electron microscopy to observe polaritons in a molybdenum oxydichloride crystal. The study demonstrates that these light-matter hybrid particles can travel longer distances and be steered more effectively than previously observed, suggesting potential applications in quantum computing and optoelectronics.

“In a study published in Nature Communications, UChicago chemists designed just such an ultrafast "camera." They used it to capture polaritons—quasiparticles made of both light and matter—moving through a special crystal that can steer their direction.”
VERIFIED
A web search result from the University of Chicago explicitly confirms that UChicago chemists published a study in Nature Communications regarding an ultrafast 'camera' to capture polaritons moving through a special crystal.
