Physics Research Fields | Major fields of physics, with subfields, theories and concepts

Modern physics research fields

Physics Research Fields

Contemporary physics research fields are divided into various disciplines that study different aspects of the physical world.

They can be broadly divided into nuclear and particle physics; condensed matter physics; atomic, molecular, and optical physics; astrophysics; and applied physics. Some physics departments also support physics education research and physics outreach.

You can fing major fields of physics, along with their subfields and the theories and concepts they employ, are shown below.
