1. The problem statement, all variables and given/known data I'm interested to know how cooper pairs are formed in low temperature superconductors. 3. The attempt at a solution My basic understanding is that electrons will repel other electrons and attract the positive ions which make up the lattice of the metal. The attraction between the +ve ions and the electrons is enough to distort the ions and hence attract other electrons. The attraction due to the displaced ions can then overcome the repulsion between electrons causing them to form cooper pairs. Does this general case apply for low temperature superconductors?
