Cooper pair

Cooper pairs are bound electrons with opposite spin and momentum

Cooper pairs consist of two electrons that are bound together at low temperatures in a specific manner. This pairing was first described by Leon Cooper in 1956. The unique binding of these electrons is crucial for the phenomenon of superconductivity.

Example

In superconductors, electrons pair up as Cooper pairs, allowing them to move through the material without resistance.

Understanding Cooper pairs is essential for explaining and harnessing superconductivity in various applications.
