COOPER PAIR Meaning and
Definition
-
A Cooper pair is a concept in the field of condensed matter physics, specifically in the theory of superconductivity. It refers to a pair of electrons in a superconductor that form a bound state with peculiar properties.
Typically, electrons in a solid material are subject to scattering due to interactions with the lattice vibrations, which results in resistance and energy loss. However, in a superconductor at low temperatures, electrons form tightly bound pairs known as Cooper pairs, named after the physicist Leon Cooper who first proposed their existence.
Cooper pairs are formed due to the attractive interaction between electrons caused by lattice vibrations known as phonons. This interaction allows electrons to overcome their repulsion and form a coherent state with correlated motion. The binding energy of the Cooper pairs is much stronger than the thermal energy, preventing their dissociation.
One of the significant characteristics of Cooper pairs is their ability to move through the lattice without scattering. This leads to the phenomenon of superconductivity, where electric current can flow indefinitely in a superconductor without any resistance. Cooper pairs can carry the current while maintaining their coherence, creating a unique quantum state with zero electrical resistance.
Understanding the behavior and nature of Cooper pairs is crucial in the study of superconductivity, as they play a pivotal role in the macroscopic quantum phenomena observed in superconducting materials.

Etymology of COOPER PAIR
The term "cooper pair" is actually named after the physicist Leon Cooper, who is one of the three scientists awarded the Nobel Prize in Physics in 1972 for their theory explaining the phenomenon of superconductivity.
In 1956, Leon Cooper, John Bardeen, and John Robert Schrieffer developed the BCS theory, which stands for Bardeen, Cooper, and Schrieffer theory. This theory describes how electrons in a superconducting material can form pairs, now known as Cooper pairs, which can move through the material without any resistance. Cooper pairs are composed of two electrons with opposite spins and momenta, and they interact with the lattice vibrations, or phonons, in the material.
So, the term "cooper pair" is simply named after Leon Cooper, one of the physicists who helped develop the theory of superconductivity.
