1. quasiparticle

   A quasiparticle is a disturbance or excitation in a medium that behaves as if it is a particle. It is an emergent phenomenon that occurs when a microscopically complicated system, such as a solid, behaves as if it contained different weakly interacting particles in free space. Quasiparticles are used in various fields of physics like solid-state physics, quantum field theory, and particle physics. Examples include phonons, holes, and magnons.

1. Quasiparticle

   In physics, quasiparticles and collective excitations are emergent phenomena that occur when a microscopically complicated system such as a solid behaves as if it contained different weakly interacting particles in free space. For example, as an electron travels through a semiconductor, its motion is disturbed in a complex way by its interactions with all of the other electrons and nuclei; however it approximately behaves like an electron with a different mass traveling unperturbed through free space. This "electron" with a different mass is called an "electron quasiparticle". In an even more surprising example, the aggregate motion of electrons in the valence band of a semiconductor is the same as if the semiconductor contained instead positively charged quasiparticles called holes. Other quasiparticles or collective excitations include phonons, plasmons, and many others. These fictitious particles are typically called "quasiparticles" if they are fermions, and called "collective excitations" if they are bosons, although the precise distinction is not universally agreed.
