Solid-state physics is a branch of physics that deals with the study of solid materials, particularly their properties and behaviors at the atomic and molecular level. This field encompasses a wide range of topics, including the structure, dynamics, and interactions of solid materials, with the goal of understanding how these properties arise from the arrangement and behavior of their constituent atoms and molecules.
