Why are Bose Einstein condensates the opposite of plasma?
Bose-Einstein Basics The molecules get denser or packed closer together. If plasmas are super hot and super excited atoms, the atoms in a Bose-Einstein condensate (BEC) are total opposites. They are super unexcited and super cold atoms.
Is Bose-Einstein condensate a plasma?
It may not be seen widely in the earth but it is to believe that in the universe everything is made up of plasma. Bose-Einstein Condensate (BEC): They are considered as the fifth states of matter after the plasma. They are a group of atoms cooled to within a hair of absolute zero.
How is Bose-Einstein condensate different from other states of matter?
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. Instead, the atoms fall into the same quantum states, and can’t be distinguished from one another.
What is Bose-Einstein condensate in matter?
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.
How plasma and Bose Einstein condensates are different from the 3 states of matter we normally talk about?
Plasmas tend to form at high temperature, since electrons then come off atoms leaving charged ions. Bose condensates form at low temperature, since at high temperatures more states are available to the atoms.
What is 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. The above figure shows the result of such a measurement.
