What are the characteristics of Bose-Einstein condensate?
What are the characteristics of Bose-Einstein condensate?
The most obvious property of a BEC is that a large fraction of its particles occupy the same, namely the lowest, energy state. In atomic condensates this can be confirmed by measuring the velocity distribution of the atoms in the gas.
What is the condition of Bose Einstein condensation?
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 is Bose-Einstein condensate theory?
A Bose-Einstein condensate is a group of atoms cooled to within a hair of absolute zero. When they reach that temperature the atoms are hardly moving relative to each other; they have almost no free energy to do so. At that point, the atoms begin to clump together, and enter the same energy states.
What are the properties of Bose-Einstein condensate for kids?
Bose-Einstein Condensates Facts: – Bose-Einstein Condensates are super unexcited and super cold atoms. This fifth state of matter happens at extremely low temperatures. The matter needs to be cooled to near absolute zero. Boson can be defined as a group of atoms cooled to within a hair of absolute zero.
Why is it called Bose-Einstein condensate?
This state was first predicted, generally, in 1924–1925 by Albert Einstein following and crediting a pioneering paper by Satyendra Nath Bose on the new field now known as quantum statistics.
What is the shape of BEC?
They have no definite shape but they have a definite volume. They are, BEC(Bose-Einstein Condensate), Solid, Liquid, Gas, and Plasma.
What is the difference between plasma and Bose-Einstein condensate?
The main difference between plasma and Bose-Einstein condensate is that the plasma state contains a gas of ions and free electrons, whereas Bose-Einstein condensate contains a gas of bosons at low densities, which is cooled to a low temperature close to absolute zero.
