Metal Superconductors and Negative Temperature

In summary, negative temperatures can only exist in certain systems with limited energy states, but superconductors are not one of these systems. Therefore, taking a metal superconductor below zero to a negative temperature would not cause it to lose its superconductivity.

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

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.
 

What are metal superconductors?

Metal superconductors are materials that exhibit zero electrical resistance at very low temperatures. This means that electric current can flow through them without any energy loss, allowing for efficient transmission of electricity.

How do metal superconductors work?

Metal superconductors work by forming a lattice structure of atoms that allows for the movement of electrons without any resistance. This lattice structure is disrupted at higher temperatures, causing the material to lose its superconducting properties.

What is negative temperature?

Negative temperature refers to a temperature scale where the temperature decreases as the energy of a system increases. This is the opposite of our everyday experience, where higher energy usually corresponds to higher temperature.

How are metal superconductors related to negative temperature?

Metal superconductors can exhibit negative temperature behavior when they are cooled below their critical temperature. At this point, the electrons in the material behave in a unique way, leading to a decrease in temperature as energy increases.

What are the potential applications of metal superconductors and negative temperature?

The potential applications of metal superconductors and negative temperature include more efficient electrical transmission, faster and more powerful computing devices, and advanced medical imaging technologies. They also have potential uses in quantum computing and high-energy physics research.
