The Quantum Chemistry series

Six chained courses, from writing your first SCF to research practice. Each has a full syllabus; planned material is visible before it lands.

  1. I Quantum Chemistry I — Hartree-Fock from Nothing 11 units · 51 items live Variational principle → integrals → SCF, with 11 programs you write and a wasm SCF you can run.
  2. II Quantum Chemistry II — The Correlation Problem 6 units · 10 items live · 10 planned What the mean field misses and every strategy for buying it back: CI, MPn, coupled cluster, CASSCF.
  3. III Quantum Chemistry III — Density Functional Theory 7 units · syllabus up · 19 planned The workhorse of modern practice: Hohenberg-Kohn, Kohn-Sham, the functional zoo, and where it lies.
  4. IV Quantum Chemistry IV — The Machinery 6 units · syllabus up · 20 planned Angular momentum integrals, DIIS, gradients, geometry optimization, properties — what makes codes real.
  5. V Quantum Chemistry V — Research Practice 6 units · syllabus up · 15 planned Method selection, basis-set craft, benchmarking discipline, and a reproduce-a-paper capstone.
  6. VI Quantum Chemistry VI — Frontiers 4 units · syllabus up · 9 planned Electives: quantum Monte Carlo, periodic systems, relativistic effects, excited states beyond CIS.
