University-level solid state physics notes covering crystal structures, band theory, and superconductivity.

• Crystal Structures: Lattices, unit cells, reciprocal lattice, diffraction
• Lattice Dynamics: Phonons, thermal properties, specific heat
• Electronic Structure: Band theory, Fermi surface, semiconductors
• Superconductivity: BCS theory, critical temperature, Meissner effect

• Quantum mechanics (wave functions, operators, perturbation theory)
• Statistical mechanics (ensembles, partition functions)
• Electromagnetism (Maxwell”s equations, dielectrics)
• Linear algebra (vectors, matrices, Fourier transforms)

Start with crystal structures to build foundational knowledge, then progress to electronic band structure and superconductivity. Each section includes worked examples and practice problems.

Use the sidebar to browse topics, or start with the introductory pages linked from the sidebar.

Each section includes:

• Detailed explanations of key concepts
