What happens to the particles in Bose-Einstein condensate?
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.
What happens to electrons in Bose-Einstein condensate?
This is ok because the density of a BEC is so much lower of the liquid of solid phase of the same species of atoms. Thus the answer to your question is that nothing happens to the electrons, they keep orbiting the nuclei at their undisturbed orbits.
What does Bose-Einstein condensate look like in real life?
It looks like a dense little lump in the bottom of the magnetic trap/bowl; kind of like a drop of water condensing out of damp air onto a cold bowl. When it first forms, though, the condensate is still surrounded by the normal gas atoms, so it looks a bit like a pit inside a cherry.
Does BEC have a fixed shape?
They atoms in a liquid slide past each other. They have no definite shape but they have a definite volume. They are, BEC(Bose-Einstein Condensate), Solid, Liquid, Gas, and Plasma.
What are examples of Bose-Einstein condensates?
Two examples of materials containing Bose-Einstein condensates are superconductors and superfluids. Superconductors conduct electricity with virtually zero electrical resistance: Once a current is started, it flows indefinitely. The liquid in a superfluid also flows forever.
What is the Bose-Einstein condensate?
Eric A. Cornell of the National Institute of Standards and Technology and Carl E. Wieman of the University of Colorado at Boulder led a team of physicists at JILA, a joint institute of NIST and CU-Boulder, in a research effort that culminated in 1995 with the creation of the world’s first Bose-Einstein condensate—a new form of matter.
What is the significance of Bose-Einstein statistics?
Bose-Einstein statistics dramatically increase the chances of finding more than one atom in the same state, and we can think of the matter waves in a Bose gas as “oscillating in concert”. The result is Bose-Einstein condensation, a macroscopic occupation of the ground state of the gas.
What is the Bose-Einstein theory of matter?
Einstein then extended Bose’s ideas to matter in two other papers. The result of their efforts is the concept of a Bose gas, governed by Bose–Einstein statistics, which describes the statistical distribution of identical particles with integer spin, now called bosons. ), are allowed to share a quantum state.
What is the difference between the Bose-Einstein and Jin-DeMarco experiments?
While the Bose-Einstein experiments used one class of quantum particles known as bosons, Jin and DeMarco cooled atoms that are fermions, the other class of quantum particles found in nature. This was important to physicists because the basic building blocks of matter—electrons, protons and neutrons — are all fermions.
