In the Bogoliubov theory a condensate initially prepared in its ground state\ndescribed by stationary Bogoliubov vacuum and later perturbed by a\ntime-dependent potential or interaction strength evolves into a time-dependent\nexcited state which is dynamical Bogoliubov vacuum. The dynamical vacuum has ...

The meaning of BOSE-EINSTEIN CONDENSATE is a state of matter that occurs when a set of atoms is cooled almost to absolute zero in which a statistical description of the positions of the atoms implies that they physically overlap each other and in effect
Bose–Einstein condensate A Bose–Einstein condensate (BEC) is a state of matter formed by a system of bosons confined in an external potential and cooled to
Einstein adopts the idea, extends it to atoms and thus predicts the existence of the phenomenon which will later be called the Bose-Einstein condensate. The full-spin subatomic particle was called a boson by Paul Dirac in honor of Satyendranath Bose. ...

These combined techniques allowed the researchers to observe what happens when monopoles are left to evolve in a Bose–Einstein condensate. “The newest aspect of our research is the ability to create monopoles consistently enough for us to observe their time evolution,” Hall explains. “We need...

(Image credit: NIST/JILA/CU-Boulder - NIST Image) The Bose-Einstein condensate (BEC) is one of the five primary states of matter. In it, atoms reach such low energies that the rules of quantum mechanics dictate that they stop acting as individual atoms and behave like a single "super ...
