Bose-Einstein condensate created at room temperature

Instead of atoms, condensation was achieved using quasiparticles.

Bose-Einstein condensation is a dramatic phenomenon in which many particles act as though they were a single entity. The first Bose-Einstein condensate produced in the laboratory used rubidium atoms at very cold temperatures—work that was awarded the 2001 Nobel Prize in physics. Other materials, like superconductors, exhibit similar behavior through particle interactions.

These systems typically require temperatures near absolute zero. But Ayan Das and colleagues have now used a nanoscale wire to produce an excitation known as a polariton. These polaritons formed a Bose-Einstein condensate at room temperature, potentially opening up a new avenue for studying systems that otherwise require expensive cooling and trapping.
