Comments on: 227. Video of the day: Meissner effect in superconductors http://www.nonequilibrium.net/video-day-superconductors/ Cosmology, turbulence, markets, non-equilibrium QFT and much more.

Somehow, when I wrote this, I was thinking about cuprates with [tex]T_c[/tex] higher than 100 K. Cheers, Dmitry. Agree, fixed.

Otherwise one would be using something with much lower boiling temperature like liquid helium (4.22K).

Cheers, Dmitry.

Do you have a more direct link?

No, I don’t – what I kept in mind is dual Meissner effect.

Cheers,
