In this lecture, we delve into the Free Electron Gas Model, a cornerstone of solid-state physics, integrating classical and quantum perspectives. Explore the evolution from the Drude model to the quantum mechanical enhancements introduced by Sommerfeld. Learn how the Schrödinger equation applies to free electrons in metals, derive energy levels, and understand key concepts like the Fermi energy, Fermi surface, and degeneracy pressure. Discover how this model explains conduction properties and the physics of white dwarf stars. Real-world example: Copper. Perfect for physics enthusiasts, undergraduate students, and researchers in material science!
