The Bc() curves of most superconductors have shapes close to simple parabolas. Suppose that Bc() = Bc0[1

The Bc(τ) curves of most superconductors have shapes close to simple parabolas. Suppose that

Bc(τ) = Bc0[1 – (τ/τc)2]

Assume that Cs vanishes faster than linearly as τ → 0. Assume also that CN is linear in τ, as for a Fermi gas (Chapter 7). Draw on the results of problem 6 to calculate and plot the τ dependences of the two entropies, the two heat capacities, and the latent heat of the transition. Show that CS(τc)/CN(τc) = 3.
