- Solid-state physics
Solid-state physics, the largest branch of
condensed matter physics , is the study of rigidmatter , orsolid s. The bulk of solid-state physics theory and research is focused oncrystal s, largely because theperiodicity ofatom s in a crystal — its defining characteristic —facilitates mathematical modeling, and also because crystalline materials often have electrical, magnetic, optical, or mechanical properties that can be exploited forengineering purposes.The framework of most solid-state physics theory is the Schrödinger (wave) formulation of non-relativistic
quantum mechanics .Bloch's theorem , which characterizes thewavefunction s ofelectron s in a periodicpotential , is an important starting point for much analysis. Since Bloch's theorem applies only to periodic potentials, and since unceasing random movements of atoms in a crystal disrupt periodicity, this use of Bloch's theorem is only an approximation, but it has proven to be a tremendously valuable approximation, without which most solid-state physics analysis would be intractable. Deviations from periodicity are treated by quantum mechanical perturbation theory.Topics
