What is the Difference Between Solid State Physics and Condensed Matter Physics? There are some models that are helpful in this theory, such as the Drude model, band structure, density functional theory, etc. Theoretical condensed matter physics involves the use of theoretical models to understand the properties of the state of matter. We can perform experiments for measuring various material properties through the application of quantum mechanics, electromagnetism, statistical mechanics, etc. However, there can be some exotic condensed phases which include the superconducting phase, Bose-Einstein condensate, etc. These are the systems consisting of strong interactions between them. In addition, condensed matter physics deals with condensed phases of matter. The properties of these phases arise from electromagnetic forces between the atoms. This mainly includes the solid and liquid phases. What is Condensed Matter Physics?Ĭondensed matter physics is a field of physics that deals with the macroscopic and microscopic physical properties of matter. Modern research areas of solid-state physics include high-temperature superconductivity, quasicrystals, spin glass, strongly correlated materials, nanomaterials, etc. We can investigate this structure using a range of crystallographic techniques such as X-ray crystallography, neutron diffraction, and electron diffraction. Moreover, there can even be Van der Waals interactions between atoms if we consider noble gas atoms.įurthermore, the properties of a particular material depend on its crystal structure. There can be ionic bonds, covalent bonds, or metallic bonds between these atoms. In a crystal, the forces between atoms can occur in different forms. This is because the periodic arrangement of atoms in a crystal tends to facilitate mathematic modeling.
As a general theory, solid-state physics focuses on crystals. These atoms can regularly rearrange during a chemical reaction, depending on the type of solid and the reaction conditions. These interactions can produce mechanical, electrical, thermal, optical, and magnetic properties of the solid material. Usually, solid materials contain densely packed atoms that can interact intensely. Moreover, this branch of physics also has applications directly in the technology of transistors and semiconductors. Therefore, solid-state physics can derive a theoretical basis from material science. This branch of physics tends to study the large-scale properties of solid materials that result from atomic-scale properties.
We can describe it as the largest branch of condensed matter physics. Solid state physics involves the study of rigid matter or solids with the use of quantum mechanics, crystallography, electromagnetism, and metallurgy. Summary – Solid State Physics vs Condensed Matter Physics What is Solid State Physics? Solid State Physics vs Condensed Matter Physics in Tabular Formĥ. Condensed matter physics is a field of physics that tends to deal with the macroscopic and microscopic physical properties of matter.
The key difference between solid state physics and condensed matter physics is that solid state physics studies the properties of solid structures such as crystals, whereas condensed matter physics studies both solid and liquid systems.
