What is another word for quasiparticle?
Pronunciation: [kwˈe͡ɪza͡ɪpˌɑːtɪkə͡l] (IPA) 
Quasiparticles are theoretical entities that behave like particles in certain conditions, but are not actual particles. Some synonyms for quasiparticle include quasi-fermion, quasi-boson, collective excitation, excitation mode, and quasiparticle mode. These terms refer to different manifestations of quasiparticles in different physical systems. Quasi-fermions are quasiparticles that obey Fermi-Dirac statistics, while quasi-bosons obey Bose-Einstein statistics. Collective excitations are coherent motions of groups of particles, while excitation modes refer to the various ways in which a physical system can be excited. Quasiparticle mode is a generic term for any type of quasiparticle. All these synonyms capture the essence of quasiparticles, which are virtual particles that serve as a useful tool for studying complex many-body systems.
