= Bose–Einstein condensation of quasiparticles
{wiki=Bose–Einstein_condensation_of_quasiparticles}
Bose-Einstein condensation (BEC) of quasiparticles refers to a phenomenon where particles known as quasiparticles, which can emerge in certain condensed matter systems, occupy the same quantum state at low temperatures, leading to macroscopic quantum phenomena. Quasiparticles are not fundamental particles but instead are collective excitations that arise from the interactions between many particles in a medium.
