Physics

An advanced degree in physics at Caltech is contingent upon an extensive research achievement. Students in the program are expected to join a research group, carry out independent research, write publications for peer-reviewed journals as well as a thesis. The thesis work is then presented and evaluated by a Caltech thesis committee in a public defense. Initially, students are required to consolidate their knowledge by taking advanced courses in at least six subfields of physics. Students must also pass a written candidacy exam in both classical physics and quantum mechanics in order to progress into the research phase of the degree.

Graduates of our program are expected to have extensive experience with modern research methods, a broad knowledge of contemporary physics, and the ability to perform as independent researchers at the highest intellectual and technical levels.

The Advanced Physics Requirement is really a breadth requirement; it's purpose is to make sure students graduating from Caltech leave with a fairly broad knowledge of physics.  At the same time, students can choose what courses they take to satisfy this requirement, following their personal interests.

Course Substitutions for the Advanced Physics Requirement 
--What counts for what...

The Advanced Physics categories: 
Students need to take a minimum of a one-quarter course in six of the following eight categories:

• Elementary Particle Physics (EP)
• Nuclear Physics (NP)
• Atomic/Molecular/Optical Physics (AMO)
• Condensed Matter Physics (CMP)
• Gravitational Physics (GR)
• Astrophysics (AP)
• Mathematical Physics (MP)
• Interdisciplinary Physics (ID)

Acceptable courses for the Advanced Physics requirement:

• Ph101/Order-of-magnitude -- counts for ID or AP
