Can I touch Bose Einstein condensate?

Can I touch Bose Einstein condensate?

Bose Einstein condensates exist on microscopic sizes in nature given by the coherence length. They retain the properties of the substance or radiation they are composed of but they cannot be touched because they reject changes in energy and momentum.

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.

Which gas is used in Bose Einstein condensation?

Superfluid helium-4 Superfluid helium has many unusual properties, including zero viscosity (the ability to flow without dissipating energy) and the existence of quantized vortices. It was quickly believed that the superfluidity was due to partial Bose–Einstein condensation of the liquid.

What makes Bose Einstein condensate so weird?

Core Concept: How Bose–Einstein condensates keep revealing weird physics. When bosonic atoms are cooled to form a condensate, they can lose their individuality. They behave like one big collective superatom, analogous to how photons become indistinguishable in a laser beam. But it’s even weirder than that.

What is the Bose-Einstein condensate used for?

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 fermionic condensate look like?

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.

How long does a Bose Einstein condensate last?

The result was a Bose-Einstein condensate of about 2,000 rubidium atoms that lasted for 15 to 20 seconds. New machines can now make condensates of much greater numbers of atoms that last up to three minutes.

Can iron kill a Bose-Einstein condensate?

Indeed, magnetic stray fields induced by iron could disrupt the traps which are usually required to prevent Bose–Einstein condensates from touching the walls of the “thermos.” Hence, iron could “kill” the condensate.

Why can’t Bose–Einstein condensates touch the walls of the thermos?

A little truth is contained in the hand-grenades made from iron particles that are used against the condensates in the movie. Indeed, magnetic stray fields induced by iron could disrupt the traps which are usually required to prevent Bose–Einstein condensates from touching the walls of the “thermos.”

Why does a Bose-Einstein condensate behave like a super atom?

That’s why the atoms in a Bose-Einstein condensate behave like “super atoms.”. When one tries to measure where they are, instead of seeing discrete atoms one sees more of a fuzzy ball. Other states of matter all follow the Pauli Exclusion Principle, named for physicist Wolfgang Pauli.
