Atomic, Molecular, and Optical Physics (AMO): The study of atoms, simple molecules, electrons and light, and their interactions.

Astronomy and Cosmology (AST): The study of space,  the universe as a whole, including its origins and evolution, the physical properties of objects in space and computational astronomy.

Biological Physics (BIP): The study of the physics of biological processes.

Computational Physics and Astrophysics (COM): A study that applies the discipline and techniques of computer science and mathematics to solve large and complex problems in Physics and Astrophysics. 

Condensed Matter and Materials (MAT)The study of the properties of solids and liquids. Topics such as superconductivity, semi-conductors, complex fluids, and thin films are studied.

Instrumentation (INS): Instrumentation is the process of developing means of precise measurement of various variables such as flow and pressure while maintaining control of the variables at desired levels of safety and economy. 

Magnetics, Electromagnetics and Plasmas (MAG): The study of electrical and magnetic fields and of matter in the plasma phase and their effects on materials in the solid, liquid or gaseous states.

Mechanics (MEC)Classical physics and mechanics, including the macroscopic study of forces, vibrations and flows; on solid, liquid and gaseous materials.

Nuclear and Particle Physics (NUC): The study of the physical properties of the atomic nucleus and of fundamental particles and the forces of their interaction.

Optics, Lasers, and Masers (OPT): The study of the physical properties of light, lasers and masers.

Quantum Computation (QUA): The study of the laws of quantum mechanics to process information. This includes studies involving the physics of information processing, quantum logic, quantum algorithms, quantum error correction, and quantum communication.

Theoretical Physics (THE)The study of nature, phenomena and the laws of physics employing mathematical models and abstractions rather than experimental processes. 

Other (OTH)Studies that cannot be assigned to one of the above subcategories.
