Would someone explain me superconductivity IN ATOMIC WORLD? if this doesn't belong in quantum physics I am sorry admin
On the other hand, there is a class of properties that are independent of the underlying material. For instance, all superconductors have exactly zero resistivity to low applied currents when there is no magnetic field present or if the applied field does not exceed a critical value. The existence of these "universal" properties implies that superconductivity is a thermodynamic phase, and thus possesses certain distinguishing properties which are largely independent of microscopic details.

Superconductivity is a phenomenon in which certain materials exhibit zero electrical resistance when cooled below a certain temperature, known as the critical temperature. This allows for the flow of electricity with 100% efficiency, without any energy loss.
Superconductivity is a result of a quantum mechanical phenomenon called Cooper pairing, where electrons form pairs and move together without resistance. This is made possible by the lattice structure of certain materials, which allows for the smooth flow of electrons.
The most well-known application of superconductivity is in magnetic resonance imaging (MRI) machines, which use superconducting magnets to generate strong magnetic fields. Superconducting materials also have potential uses in power transmission, transportation, and computing.
Superconductors can be classified into two types: Type I and Type II. Type I superconductors are pure metals and have a sharp transition to superconductivity at the critical temperature. Type II superconductors are typically alloys or compounds and have a more gradual transition to superconductivity at the critical temperature.
The main challenge in achieving room temperature superconductivity is finding materials that can maintain their superconducting properties at higher temperatures. This requires a deep understanding of the mechanisms behind superconductivity and the ability to engineer materials with the desired properties.
