Bose–Einstein condensation of quasiparticles

Bose-Einstein condensation (BEC) is a phase transition that happens when particles, such as atoms or quasiparticles, are cooled to temperatures near absolute zero. At these ultralow temperatures, particles occupy the same quantum state, leading to macroscopic quantum coherence.

Quasiparticles, which are collective excitations in materials, can also undergo Bose-Einstein condensation. These particles, including those with integer spins, behave similarly to traditional particles and can be expected to obey Bose-Einstein statistics. This phenomenon has been both predicted and observed in various quasiparticles.

The study of Bose-Einstein condensation continues to be an active field of research. Scientists are exploring the conditions for condensation of different quasiparticles, which can lead to new insights and applications in materials science and quantum physics.
