Quantum Simulation Reveals Fundamental Ceiling on Electrical Resistance
Summary
Physicists have discovered a fundamental limit to electrical resistance using a quantum simulation with ultracold atoms. The research shows that there is a maximum possible resistivity caused by electron collisions, beyond which resistance cannot increase. This ceiling on resistivity arises from quantum mechanical effects where particles behave as if they are larger than their actual size, increasing collision likelihood. The finding provides fundamental insights into the nature of electrical resistance and could have implications for understanding conductivity in materials.
