It's a simple idea, where Einstein had a thought experiment about simply adding a few more particles to a system. And they all collapse into one state, which is the essence of a Bose-Einstein condensate. He had that idea, and it took 75 years before we could actually make them into a real experiment rather than just a thought experiment.
Condensado de BoseEinstein qué es y por qué es tan importante
Bose-Einstein condensate (BEC), a state of matter in which separate atoms or subatomic particles, cooled to near absolute zero (0 K, − 273.15 °C, or − 459.67 °F; K = kelvin), coalesce into a single quantum mechanical entity—that is, one that can be described by a wave function—on a near-macroscopic scale. This form of matter was predicted in 1924 by Albert Einstein on the basis of.

Bose-Einstein condensation is an exotic quantum phenomenon that was observed in dilute atomic gases for the first time in 1995, and is now the subject of intense theoretical and experimental study. Figure 1 The set-up for evaporative cooling from the cloverleaf magnetic trap at MIT. The central (curvature) coils provide axial confinement while.

Computer model of a Bose-Einstein condensate shows wave-like structure of atoms near absolute zero. (NASA/NIST) Sometimes referred to as the 'fifth state of matter ', a Bose-Einstein Condensate is a state of matter created when particles, called bosons, are cooled to near absolute zero (-273.15 degrees Celsius, or -460 degrees Fahrenheit).

The atoms within the condensate obey the laws of quantum physics and are as close to absolute zero—minus 273.15 Celsius or minus 459.67 degrees Fahrenheit—as the laws of physics will allow. The physicists likened it to an ice crystal forming in cold water. "It really is a new form of matter," Wieman said. "It behaves completely differently.

Estado condensado de BoseEinstein
In 1924-25 Bose and Einstein [4, 5] realized that, when cooled to very low temperatures, an ideal gas of non-interacting bosons can undergo a peculiar phase transition, later called Bose-Einstein condensation.The resulting state of matter is characterized by a macroscopic population of the lowest energy state of the system, and it is a genuinely quantum phenomenon arising due to the.

Updated on February 06, 2018. Bose-Einstein condensate is a rare state (or phase) of matter in which a large percentage of bosons collapse into their lowest quantum state, allowing quantum effects to be observed on a macroscopic scale. The bosons collapse into this state in circumstances of extremely low temperature, near the value of absolute.

Schematic Bose-Einstein condensation versus temperature of the energy diagram [clarify]. 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.

1 Introduction. Bose-Einstein condensation is a quantum phenomenon in Bose gases in which a large number of bosons simultaneously occupy the ground state of a system. Bose-Einstein condensates were predicted in 1925 by Bose and discovered experimentally 70 years later by Weimann, Cornell and Ketterle who shared the Nobel prize for their.
