The Materials Maze
Catalysts, superconductors, battery materials, magnetic compounds, and transition-metal oxides derive useful behaviour from electrons acting collectively. Strong correlation can make a compact Hamiltonian into a difficult many-body calculation.
Unit 7 separates two jobs. It solves a two-site Hubbard model by exact classical diagonalisation, then feeds one known energy into a compiled three-bit quantum phase-estimation circuit.
