Physics:Quantum materials/superconductor
From HandWiki Test
A superconductor is a material that exhibits zero electrical resistance and expels magnetic fields when cooled below a critical temperature.
A superconductor expels magnetic fields (Meissner effect) and allows current to flow without resistance.
Description
In the superconducting state, electrons form correlated pairs and move coherently through the material without energy loss. This behavior arises from quantum effects that extend across the entire material.
Superconductivity is a macroscopic quantum phenomenon and is closely related to the structure of the material’s band structure.
Properties
- zero electrical resistance
- expulsion of magnetic fields
- occurs below a critical temperature
- macroscopic quantum state
