What are the properties of plasma and Bose Einstein condensate?

What are the properties of plasma and Bose Einstein condensate?

Summary – Plasma vs Bose-Einstein Condensate The key difference between plasma and Bose Einstein condensate is that 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.

What is Bose Einstein condensate BEC and fermionic condensate?

Both are made of atoms that coalesce at low temperatures to form a single object. In a BEC, the atoms are bosons. In a fermionic condensate the atoms are fermions. So, e.g., ordinary sodium atoms are bosons, and they can merge to become Bose-Einstein condensates.

Can Bose Einstein condensate conduct electricity?

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 are the properties of fermionic condensate?

Fermionic condensates are a type of superfluid. As the name suggests, a superfluid possesses fluid properties similar to those possessed by ordinary liquids and gases, such as the lack of a definite shape and the ability to flow in response to applied forces.

What is BEC 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 do plasma and Bose Einstein condensation form?

When the atoms become very cold, many of them go into that specific state. 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 Bose in steam condensate?

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 are properties of gases?

Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form.

What are the properties of a Bose Einstein condensate?

What are the properties of a Bose Einstein Condensate? i. What are the properties of a 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 are the properties of a BEC?

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.

What is quantum tunneling in Bose Einstein condensates?

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. A fraction of the condensate “tunnels” through this barrier.

What happens when two clouds of Bose condensed atoms overlap?

When we overlap two clouds of Bose condensed atoms their densities do not simply sum up, but they interfere with each other creating a spatial density profile with periodically arranged maxima and minima in analogy to two interfering light beams which produce a similar scheme on a screen.
