Description
Introduction:
Electronic band structure, crystalline order, phonons, harmonic oscillators, second quantization.
Electronic order by repulsive interactions:
From Hubbard electrons to Heisenberg spins, ferro- and antiferromagnetic order, spin waves and Holstein-Primakoff, semi-classical mean-field theory, Random-Phase-Approximation (RPA).
Attractive interactions:
