To kill a quasiparticle: A quantum whodunit

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 particles as 'quasiparticles'.

Best evidence yet for existence of anyons

A small team of researchers at Purdue University has found the strongest evidence yet of the existence of abelian anyons. They have written a paper describing experiments they conducted designed to reveal the existence of ...

Anyon evidence observed using tiny anyon collider

A team of researchers from Sorbonne Université, CNRS and Ecole Normale Supérieure has reported observational evidence of a quasiparticle called an anyon. In their paper published in the journal Science, the team describes ...

Massive photons in an artificial magnetic field

An international research collaboration from Poland, the UK and Russia has created a two-dimensional system—a thin optical cavity filled with liquid crystal—in which they trapped photons. As the properties of the cavity ...

Excitons will shape the future of electronic devices

Excitons are quasiparticles made from the excited state of electrons and—according to research being carried out EPFL—have the potential to boost the energy efficiency of our everyday devices.

Oscillating quasiparticles: the cycle of decay and rebirth

Decay is relentless in the macroscopic world: Broken objects do not fit themselves back together again. However, other laws are valid in the quantum world: New research shows that so-called quasiparticles can decay and reorganize ...

New material also reveals new quasiparticles

Researchers at PSI have investigated a novel crystalline material that exhibits electronic properties that have never been seen before. It is a crystal of aluminum and platinum atoms arranged in a special way. In the symmetrically ...
