How is Bose Einstein condensate useful?
An important effect, that can observed in Bose Einstein Condensates, is quantum mechanical tunneling. It means that a small fraction of the condensate can overcome a barrier that could not be overcome by a classical particle. This property gives rise to other quantum mechanical effects like the Josephson-Effect.
What are the examples of BEC in real life situation?
A BEC ( Bose – Einstein condensate ) is a state of matter of a dilute gas of bosons cooled to temperatures very close to absolute zero is called BEC. Examples – Superconductors and superfluids are the two examples of BEC.
What can you do with Bose Einstein condensate?
The proposed areas of applications of bose-einstein condensate are:
- Quantum information processing- concept of quantum computer.
- Precision measurement by development of most sensitive detectors using BEC.
- Development of optical lattices which could be easily modifiable by varying the interplanar spacing etc.
What happens if we touch Bose Einstein condensate?
The process of cooling discards the majority of the particless. Therefore the total amount of the condensed matter is tiny with a very low density. If you were to get into contact with a cloud of BEC, your body heat would heat up the cold matter in no time, effectivelly destroying the condensate.
What is Bose-Einstein state of matter in chemistry?
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 plasma and BEC?
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. For example, we can take Helium.
What is Bose Einstein condensate in simple words?
Bose–Einstein condensate (BEC) is what happens to a dilute gas when it is made very cold, near absolute zero (0 K which equals −273.15 °C or −459.67 °F). It forms when the particles that make it up have very low energy. A Bose–Einstein condensate is a change of state.
What is an example of Bose Einstein condensate?
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.
Why does Bose-Einstein condensation happen?
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. To make a Bose-Einstein condensate, you start with a cloud of diffuse gas.
How does Bose-Einstein condensate feel like?
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.
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 Bose-Einstein integral of critical temperature?
When the integral (also known as Bose–Einstein integral) is evaluated with factors of and ℏ restored by dimensional analysis, it gives the critical temperature formula of the preceding section. Therefore, this integral defines the critical temperature and particle number corresponding to the conditions of negligible chemical potential
