What's Next

You have implemented the foundational equations of condensed matter physics. Here are natural next steps:

• Plasma Physics — The free electron gas in a metal is a dense, degenerate plasma. Plasma physics extends these ideas to unbound, hot ionized gases.
• Quantum Mechanics — Many condensed matter results follow from the Schrödinger equation applied to periodic potentials (Bloch's theorem).
• Statistical Mechanics — The partition function underlies the Fermi-Dirac and Bose-Einstein distributions that govern electrons and phonons.
• Materials Science — How crystal defects, grain boundaries, and doping engineer the properties of real materials.
