bose-einstein condensate: meaning, definition, pronunciation and examples

They are primarily used in fundamental research to study quantum mechanics on a macroscopic scale, and have applications in precision measurement (e.g., atom interferometry) and quantum computing simulations.

It was first predicted theoretically by Satyendra Nath Bose and Albert Einstein in the 1920s. It was first produced experimentally in 1995 by Eric Cornell, Carl Wieman, and Wolfgang Ketterle, who later received the Nobel Prize.

It is considered a distinct fifth state of matter. While created from an ultracold gas, it exhibits properties unlike any classical solid, liquid, or gas, behaving as a single quantum wave.

Not with the naked eye. It is typically contained in a magnetic trap in a vacuum chamber and is observed using specialized imaging techniques like absorption imaging, which reveals its density profile.

A state of matter of a dilute gas of bosons cooled to temperatures very close to absolute zero, where a large fraction of the bosons occupy the lowest quantum state, causing macroscopic quantum phenomena.

Bose-einstein condensate is usually technical/scientific in register.
