In summary, the conversation delved into the concept of cooper pairs in superconductors and how they contribute to the phenomenon of zero electrical resistance. It was mentioned that cooper pairs are a dynamic pairing of fermions, ultimately condensing in momentum space. The conversation also touched on the idea that the condensation of cooper pairs is a result of their statistics, and not necessarily interactions between them.

I wonder do cooper pairs make cooper pair in superconductors, like two cooper pairs pair up to make another cooper pair?
I am still unclear on how this mechanism work to produce the effect of zero electrical resistance.

I supposed all the electrons are paired up in cooper pair and these cooper pairs should be paired up too. That way everything moves forward (in a supercurrent) without any scattering or loss of energy due to collision.

Electrons are fermions. Cooper pairs are bosons. The forces between them is simply different.

Cooper pairs are *dynamical* pairing of fermions. Cooper pairs being bosons ultimately condense in momentum space. There is not much use in considering pairs of bosons with [itex]\pm \vec{k}{}[/itex] since most of them will end up having the same momentum due to condensation.

I have very little understanding of the properties of elementary particles. So the idea is that once electrons formed pairs, they become bosons and from that point on, extra bonding is unnecessary to avoid scattering effect?

The condensation of Cooper pairs is a property of their statistics (Bose-Einstein ). It has nothing to do with interactions between them. In reality I think one requires some sort of repulsive interactions for condensation to occur. But at an elementary level one may think of condensation of Cooper pairs as solely due to their bosonic nature.
 

FAQ: Making Cooper Pairs of Cooper Pairs?

1. How are Cooper pairs of Cooper pairs made?

Cooper pairs of Cooper pairs are made through a process called superconductivity. This is when electrons in a material pair up and move without resistance, creating a strong current. In certain materials, these paired electrons can also form into larger pairs, known as Cooper pairs of Cooper pairs.

2. What is the significance of Cooper pairs of Cooper pairs?

Cooper pairs of Cooper pairs are significant because they provide a deeper understanding of the phenomenon of superconductivity. They also have potential applications in quantum computing and could potentially lead to the discovery of new materials with even higher superconducting properties.

3. How do scientists study Cooper pairs of Cooper pairs?

Scientists study Cooper pairs of Cooper pairs through various experimental techniques, such as scanning tunneling microscopy and spectroscopy. These techniques allow them to observe the behavior and properties of these paired electrons and gain insight into their nature.

4. Can Cooper pairs of Cooper pairs exist in all materials?

No, Cooper pairs of Cooper pairs can only exist in certain materials that exhibit superconductivity. These materials typically have a low temperature and a low electrical resistance, allowing for the formation of these larger pairs of electrons.

5. What are the potential real-world applications of Cooper pairs of Cooper pairs?

Aside from their significance in understanding superconductivity, Cooper pairs of Cooper pairs have potential applications in quantum computing. They could also lead to the discovery of new materials with even higher superconducting properties, which could have practical applications in fields such as energy transmission and storage.
