Hi everyone,
- Could you explain for me the meaning of "net" in the phrase "small net attraction between electrons" in superconductivity, (or synonym of it)?
- We usually say that BSC theory explains the superconductivity of conventional superconductors, one feature of superconductivity is zero resistivity at temperature below Tc, but I don't know how Cooper pair formation and energy gap explain this behavior explicitly, Is there any formula of resistivity which includes superconducting gap? To explain resistivity in normal state we say that there are collisions between electrons and defects, lattice but why can't we imagine Cooper pair as a particle which also collides with defects and lattice?
(In books on superconductivity author usually derive energy gap and say that there is no collision without proving)
Thank you very much.
