What would happen to a metal superconductors taken below zero to a negative temperature? Would it loose its superconductivity?

below zero to a negative temperature?
Absolute T? You do understand that's not possible?

"a system with a truly negative temperature in absolute terms on the Kelvin scale is hotter than any system with a positive temperature" http://en.wikipedia.org/wiki/Negative_temperature

That article has a number of important points that you didn't mention:

  • In physics, certain systems can achieve negative temperature
  • Most familiar systems cannot achieve negative temperatures
  • Negative temperatures can only exist in a system where there are a limited number of energy states
Superconductivity is not one of the listed, special systems, so you cannot reach negative temperature in a superconductor.
