What special properties does Bose-Einstein condensate have?

What special properties does Bose-Einstein condensate have?

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 use of 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 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 Bose temperature?

In condensed matter physics, a Bose–Einstein condensate (BEC) is a state of matter that is typically formed when a gas of bosons at low densities is cooled to temperatures very close to absolute zero (−273.15 °C or −459.67 °F).

What is Bose-Einstein condensate Upsc?

Bose-Einstein condensates (BECs) — the existence of which was predicted by Albert Einstein and Indian mathematician SatyendraNath Bose almost a century ago — are formed when atoms of certain elements are cooled to near absolute zero (0 Kelvin, minus 273.15 Celsius).

What is fermionic condensate and characteristics?

A fermionic condensate or Fermi-Dirac condensate is a superfluid phase formed by fermionic particles at low temperatures. The earliest recognized fermionic condensate described the state of electrons in a superconductor; the physics of other examples including recent work with fermionic atoms is analogous.

What is Bose Einstein condensate Wikipedia?

What is Bose Einstein Condensate and 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. BEC when reached near to temperature zero the atoms are hardly moving relative to each other since they have very less free energy to do so.

What can destroy Bose Einstein condensate?

The slightest touch of room-temperature air molecules would immediately destroy the condensates.

What is unusual about Bose Einstein condensation?

A Bose-Einstein condensate (BEC), the first of which was shown experimentally 22 years ago, isn’t your garden variety state of matter. It formed at a fraction above absolute zero and only in atoms that act like bosons, one of two types of fundamental particles.

What is the process of Bose Einstein condensate?

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 some examples of Bose Einstein condensates?

Two examples of Bose-Einstein condensates include superfluids, such as cold liquid helium, or superconductors, such as the nucleons inside a neutron star.

What is the use of Bose Einstein?

Viewed as a pure probability distribution, the Bose-Einstein distribution has found application in other fields: In recent years, Bose-Einstein statistics have also been used as a method for term weighting in information retrieval .

What state of matter is Bose Einstein?

Bose Einstein Condensate is the fifth state of matter (after solid, liquid, gas, plasma). To visualize the fifth state of matter one needs to have the cooling capacity to lower gas temperature to very near the absolute zero (less than one-millionth of a degree above absolute zero).
