For the same reason, superfluid helium-3 is not miscible with superfluid helium-4. Liquids of the same element but don't mix, amazing? Warut On Thu, Feb 7, 2013 at 7:25 AM, Henry Baker <hbaker1@pipeline.com> wrote:
I just listened to a lecture regarding supercold (micro/nano Kelvin) atoms.
I hadn't realized it before, but two different isotopes of the same element can have vastly different properties at extremely low temperatures if one is a boson and the other is a fermion.
Apparently, someone showed this happening with two different isotopes of lithium.
Can these properties be utilized to _separate_/_sort_ isotopes into the part containing the bosonic isotopes and the part containing the fermionic isotopes?
