Scientists propose super-bright light sources powered by quasiparticles

An international team of scientists is rethinking the basic principles of radiation physics with the aim of creating super-bright light sources. In a new study published in Nature Photonics, researchers from the Instituto Superior Técnico (IST) in Portugal, the University of Rochester, the University of California, Los Angeles, and Laboratoire d’Optique Appliquée in France proposed ways to use quasiparticles to create light sources as powerful as the most advanced ones in existence today, but much smaller.
