In fractional quantum Hall states - a type of collective electron state observed only in two dimensional samples at very high magnetic fields - the quasiparticles are known to have precisely a rational fraction of the electron charge, implying that they are anyons," Young said in the release.

It's here, down at the limits of physics, that solid materials give rise to so-called quasiparticles, whose unusual behavior gives them the potential to serve as the key components of quantum computers.
Quantum excitations often behave like new emergent particles--like quasiparticles, such as 'dropletons'--that give every appearance of being ordinary particles.
This tradition has now been expanded from familiar particles like electrons and protons to quasiparticles, which act like particles but aren't.
The team is currently imaging skyrmions -- quasiparticles with magnetic vortex-like configurations -- with immense appeal for future data storage and spintronic technologies.
Defining magnons as quasiparticles that describe quanta of spin waves in magneto-ordered media, Safonov says the concept allows perturbations of the magnetic material to be the represented as an evolution of magnon gas excited to some definite level or, classically, as an evolution of spin waves.

Planck was significantly supplemented and developed by another prominent German theoretical physicist Albert Einstein (1879-1955), who extended it to light radiation and introduced the concept of the flux of <<quanta of electromagnetic radiation>> for sunlight or <<photons>> peculiar quasiparticles without a rest mass [1, 2], So in physics, the concept of dualism (duality) for light, which was simultaneously a flux of quasiparticles (photons) and a set of electromagnetic waves of various lengths, was introduced.
