Quasiparticles die young, lasting far, far less than a second. Why? A new Monash University study finds a culprit beyond the usual suspect (decay into lower energy states). Identification of the new ...

Physicists have created the first Bose-Einstein condensate—the mysterious fifth state of matter—made from quasiparticles, entities that do not count as elementary particles but that can still have ...

There’s a new clique among quantum particles in a semiconductor. Electrons and positively charged holes in the material’s atomic lattice band together to create a tight-knit posse dubbed a collexon, ...

Fractional excitons: When quasiparticles that carry fractional charges pair up, new quantum particles are formed. (Courtesy: Demin Liu) A newly-discovered class of quasiparticles known as fractional ...

Analogue interaction Illustration of how an impurity atom may gradually evolve into a quasiparticle by interacting with a surrounding medium. This mechanism is similar to how an electron can distort a ...

Physicists of all stripes seem to have one thing in common: They love smashing things together. This time-honored tradition has now been expanded from familiar particles like electrons, protons, and ...

In large systems of interacting particles in quantum mechanics, an intriguing phenomenon often emerges: groups of particles begin to behave like single particles. Physicists refer to such groups of ...

Scientists have created a Bose-Einstein condensate out of excitons -- quasiparticles that combine electrons and positively charged 'holes' -- in a semiconductor. Quasiparticle Bose-Einstein ...
