Researchers have proposed a new idea for quasi particle driven ultra bright light sources, which can be used in various applications from non-destructive imaging to chip manufacturing

An international team of scientists is rethinking the fundamental principles of radiation physics, aiming to create ultra bright light sources. In a new study published in Nature Photonics, researchers from the Higher Institute of Technology in Lisbon, Portugal, the University of Rochester, the University of California, Los Angeles, and the Optical Applications Laboratory in France proposed the use of quasi particles to generate light sources, which are as powerful as the most advanced light sources today, but have much smaller volume scales.

Quasiparticles are formed by many synchronously moving electrons. They can move at any speed, even faster than light, and can withstand powerful forces similar to those near black holes.

The most fascinating thing about quasi particles is that they can move in ways that are not allowed by the laws of physics that control individual particles. The team studied the unique properties of quasi particles in plasma by running simulations on supercomputers provided by the European High Performance Computing Joint Project. They saw the application prospects of quasi particle based light sources, including non-destructive imaging for scanning viruses, understanding biological processes such as photosynthesis, manufacturing computer chips, and exploring the behavior of matter in planets and stars.

Researchers have stated that although each electron performs relatively simple motion, the total radiation of all electrons can simulate the radiation of particles moving faster than the speed of light, even if no local electron is faster than light or oscillating electrons.

Quasiparticle based light sources may have significant advantages over existing forms such as free electron lasers, as free electron lasers are scarce and large-scale, making them impractical for most laboratories, hospitals, and enterprises. According to the theory proposed by new research, quasi particles can generate incredibly bright light at short propagation distances, which may trigger widespread technological advancements in laboratories worldwide.
