Quantum obstacle course changes material from superconductor to insulator

Click For Summary
SUMMARY

Researchers at Brown University have developed a novel technique to transition materials from superconductors to insulators by utilizing a quantum obstacle course. This method effectively halts superconductivity, which is characterized by the ability to conduct electricity without resistance. The findings challenge traditional understandings of electrical conductivity and may have significant implications for future material science applications.

Researchers from Brown University have demonstrated an unusual method of putting the brakes on superconductivity, the ability of a material to conduct an electrical current with zero resistance.

"a material to conduct an electrical current with zero resistance" ? Is this not ohm's law to a logical extreme?, or am I missing something?
