Would anyone like to suggest an "easy" explanation of how superconductivity occurs? Firstly, how the Cooper pairs form and secondly why that actually results in zero resistance? This is what I understand: An electron passes through the lattice and destorts it. This creates a region of poisitive charge which accelerates a second electron towards the 1st creating the Cooper pair. Now, books also go into phonons but I don't understand why they are necessary. Also, why the formation of Cooper pairs actually results in superconductivity I dont understand at all, and few books seem to offer an explanation at all. Please help!!
