Q1. (a) The number density of free electrons in tin is 1.5 x 102⁹ m³³. Compute the penetration depth predicted by the London model, assuming that all the free electrons are superconducting. The permeability of free space (at vacuum) is a physical constant equal to approximately 4π x 10-7 henry per meter. (b) Estimate the coherence length, if Hc₁ and Hc2 are 31 and 155 oersted, respectively. (1.5/1)
