Quantum collective phenomena

Quantum collective phenomena occur when particles like atoms or electrons behave in a coordinated way due to their quantum nature, often at very low temperatures or high densities. Instead of acting independently, they move or interact as a unified whole, leading to remarkable effects such as superconductivity (zero electrical resistance) or superfluidity (frictionless flow). These phenomena demonstrate how quantum mechanics, which governs tiny particles, can produce unexpected and highly organized behaviors on a macroscopic scale, revealing the deep interconnectedness of matter at the smallest levels.
