Week 38

On Monday, we finished Wick's Theorem and discussed particle-holes/quasiparticles. That concluded the basic formalism part.

We started on the variational principle, the main engine behind computational method generation.

Thursday, we continue discussing the variational principle, and start discussing the CI method. There will be some more on quasiparticles, with normal-ordered Hamiltonians, if we get that far.

The lecture notes are updated, with a detailed proof of Wick's theorem and the material for this week, plus some of next week's material.
