227. Video of the day: Meissner effect in superconductors
Save This Post as PDFHere is the video related to the Problem N8 that we have discussed yesterday (what you see is probably high 
superconductor – the liquid that the guy uses seems to be liquid nitrogen).
The effect seems also to be related to the Problem N4 (confinement of quarks). I mentioned this idea several times on the blog, but do you really know how is it related?

It’s related in this video of mine

because it’s about Liquid Nitrogen and the band that sings it is called the LHC which is where they collide confined quarks.
Well, superconductivity is about a U(1) Higgs field, so any Higgsing – even electroweak one – is “superconductivity” and confinement is S-dual to that Higgsing in some pictures.
Do you have a more direct link?
No, I don’t – what I kept in mind is dual Meissner effect.

If the coolant is indeed liquid nitrogen (boils at 77K) and it looks like it is, then I would think that it is indeed a high-Tc material. Otherwise one would be using something with much lower boiling temperature like liquid helium (4.22K).
Agree, fixed. Somehow, when I wrote this, I was thinking about cuprates with
higher than 100 K.
Cheers,
Dmitry.
