I am researching low temperature, near absolute zero, and in particular Bose Einstein Condensate. There is a lot of research information, but it is confusing, and not explained.
Technically a BEC is formed from a gas or liquid at somewhere below 1K. The only three elements that could still be in a liquid state at <1k are Helium, Hydrogen and Neon. Hydrogen and Neon would need to be at a pressure, below atmospheric. So, these are the only three elements that can become BEC's in their natural state.
Most of the experiments using other elements, are not in their natural state, but are carried out, using a non natural vapour, of the element's atoms.
It appears to me, that Helium is the only element which naturally becomes a BEC,at atmospheric pressure, but even Wiki., when it talks about Helium's strange properties, below its Lambda point, does not mention, it becoming a BEC.
My questions are:
- Does Helium just naturally display BEC properties at <1K, or does it become a BEC?
- Are you aware of anyone lowering Hydrogen and/or Neon to a temperature where they enter a BEC state? IE. Can Hydrogen and Neon become BEC's.
- Am I assuming correctly, that H,He and Ne are the only three elements that can enter a BEC state naturally? IE. Other elements at <1K are in a solid state, and can not become a BEC.
