Bose–Einstein condensates

Definition

Bose–Einstein condensates are a state of matter in which all the constituent particles exist in their lowest energy level. The Pauli Exclusion Principle prevents more than one electron (an example of a fermion) per quantum state; however no such limit is imposed on particles known as bosons, such as helium-4 atoms.

    Flow without friction is a strange phenomenon usually seen in quantum fluids that are cooled to temperatures near absolute zero, but features of superfluidity have now been seen with polaritons at ambient conditions.

    A milestone for quantum hydrodynamics may have been reached, with experiments on a black hole-like event horizon for sound waves providing strong evidence for a sonic analogue of Hawking radiation.

    Bose–Einstein condensation in atomic gases was first observed in 1995. As we look back at the past 20 years of this thriving field, it's clear that there is much to celebrate.
