TL;DR Summary
How can we draw a Cooper pair in a band diagram?
Can we draw a Cooper pair in a band diagram? I know that Cooper pairs have very small energy (because they obey the Bose-Einstein statistics) but I was wondering if we could somehow plot in a band diagram and if yes how?
 
Physics news on Phys.org
I think that band diagram are made for to describe the conduction of different materials mainly conductors ,semi conductor and ,insulators
And their energy levels by (valance band , conduction band and forbidden energy gap)

But for the case of cooper pair its a state of superconductor which is cased due to variation in temp means low temp
but in the band diagram we don't have any representation of temp in any sort
Otherwise conductor and insulators and semi conductor request different magnitude of energy at (band gap) to jump to CD

Then they would more likely to have a number of set of different band diagram at different temperatures (states) for each material like

From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...
Hi. I have got question as in title. How can idea of instantaneous dipole moment for atoms like, for example hydrogen be consistent with idea of orbitals? At my level of knowledge London dispersion forces are derived taking into account Bohr model of atom. But we know today that this model is not correct. If it would be correct I understand that at each time electron is at some point at radius at some angle and there is dipole moment at this time from nucleus to electron at orbit. But how...
