Applied Physics is a broad field of study that lies at the intersection of physics and many other fields of science and engineering. The Applied Physics option at Caltech is accordingly a highly multi-disciplinary program that is designed to train students in a broad spectrum of physics and engineering fields at an advanced level. The goal of the doctoral program is to cultivate abilities in our graduates to apply this knowledge throughout their lives so as to make technological and scientific breakthroughs at the edge of current knowledge.

Requirements for Candidacy to the Ph.D. Degree

To be recommended for candidacy for the Ph.D. degree in Applied Physics, a student must demonstrate mastery in the following five areas of pure and applied physics:

• Classical Physics: Mechanics and Electromagnetism
• Quantum Mechanics
• Mathematical Methods
• Statistical Physics and Thermodynamics
• Biophysics, Optical Physics, Hydrodynamics, Plasma Physics, or Solid State Physics

Description of the Degree of Doctor of Philosophy (Ph.D.)

To receive the doctoral degree in Applied Physics students must demonstrate the ability to formulate and execute an original program of scientific study. As part of this, a doctoral candidate is expected to develop a deep understanding in a chosen field of specialization; to develop tools with which to assess problems outside one’s field of specialization; to develop rigor and strength in the physical sciences for self-education beyond formal training; and to develop skills to become a productive member of the community of scholars. All students wishing to enter the program must complete a series of preparatory courses, followed by an oral candidacy exam in which the student describes their proposed topic of research and is examined on their knowledge of course subject matter. Upon passing the candidacy examination, students work towards completion of a thesis in consultation with their research advisor. The doctoral degree is awarded upon approval of a written thesis by a faculty committee, and successful defense of the thesis in a final oral examination. There is no separate Master’s Program in Applied Physics. However, with the approval of the student’s advisor and the Applied Physics option representative the degree of Master of Science in Applied Physics may be awarded after the fulfillment of the course requirements.
