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 ...

Over the past decades, physicists worldwide have been trying to gain a better understanding of non-equilibrium dynamics in quantum many-body systems. Some studies investigated what are known as ...

Non-equilibrium quasiparticles are possible sources for decoherence in superconducting qubits because they can lead to energy decay or dephasing upon tunneling across Josephson junctions (JJs). Here, ...

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 ...

The macroscopic quantum condensate of electron pairs in a superconductor is represented by its order-parameter \({\Delta}_{\mathbf{k}}^\alpha \propto \langle c ...

The quasiparticle concept allows physicists to describe complex, many-body interactions in terms of the behaviour of a single particle-like entity. Usually these particles turn up in condensed-matter ...

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 ...

There’s an eerie and incredibly rare phenomenon witnessed by few that has long puzzled scientists: ball lightning. These flashes, which typically appear in the evenings during thunderstorms and look ...

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

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 ...
