Learn Super Conductors: Focus on Band Theory?

[Silverious]

Hi,

I was wondering, if I wanted to specialize in super conductors, would I have to focus on band theory?

Yes, at least to some extend (assuming you're familiar with quantum theory and basic solid state physics). Things like Bloch-waves, reciprocal space, Fermi-energy, band gap, Debye energy and electron-phonon interaction are quite important in understanding superconductors. However, I'd draw the line at $$k\cdot p$$ approximation: you won't really need that. Likewise for actually calculating complicated bandstructures in 3D.

Hope this helps!
