Why some metals have 0 resistance at 0 kelvin

Click For Summary
SUMMARY

The discussion centers on the phenomenon of superconductivity, specifically addressing why certain metals exhibit zero electrical resistance at absolute zero (0 Kelvin). It is clarified that superconductivity is not limited to 0 K, as high-temperature superconductors can transition above 100 K. The conversation distinguishes between zero resistance in metals and the criteria for superconductivity, which includes the Meissner effect among other factors.

PREREQUISITES
  • Understanding of superconductivity principles
  • Knowledge of transition temperatures in materials
  • Familiarity with the Meissner effect
  • Basic concepts of electrical resistance
NEXT STEPS
  • Research the properties of high-temperature superconductors
  • Study the Meissner effect in superconducting materials
  • Explore the BCS theory of superconductivity
  • Investigate the role of electron pairing in superconductivity
USEFUL FOR

Physicists, materials scientists, and electrical engineers interested in the mechanisms of superconductivity and its applications in technology.

Hey someone please explain why some metals have 0 resistance at 0 kelvin (absolute zero).
Please explain the complete mechanism properly.

Er... what you are describing is NOT superconductivity. Superconductivity doesn't have to occur only at 0 K. That's the whole point of this phenomenon. High Tc superconductors have a transition temperature often above 100 K!

Based on your question, I'm not sure if you're asking about the phenomenon of superconductivity, or if you want to know why metals are projected to have zero resistance at 0K. The latter isn't a superconductor because zero resistance isn't the only criteria for superconductivity (Meissner effect, etc.)

So please provide further clarification.
