The bose einstein condensate
WebIf a population of Bosons is reduced to a temperature below their condensate temperature, a new state of matter, called a Bose Einstein Condensate (BEC), is formed. Where the population of atoms takes on a wave like nature, eventually the same wave function, and a macroscopic matter wave is observable, as shown in Figure 1.

In condensed matter physics, a Bose–Einstein condensate (BEC) is a state of matter that is typically formed when a gas of bosons at very low densities is cooled to temperatures very close to absolute zero (−273.15 °C or −459.67 °F). Under such conditions, a large fraction of bosons occupy the lowest quantum … See more Bose first sent a paper to Einstein on the quantum statistics of light quanta (now called photons), in which he derived Planck's quantum radiation law without any reference to classical physics. Einstein was impressed, … See more This transition to BEC occurs below a critical temperature, which for a uniform three-dimensional gas consisting of non-interacting particles with no apparent internal degrees of freedom is given by: where: See more The Gross-Pitaevskii equation is a partial differential equation in space and time variables.
