Course Requirements for Degree
Each student is required to demonstrate proficiency in a broad range of fields of physics by obtaining honor grades (B or better) in at least eight halfcourses: a minimum of four core courses and an additional four elective courses. (Note that courses cannot double count.)
Core courses
 Advanced Quantum Mechanics I [Physics 251A] or Quantum Field Theory I [Physics 253A] or Quantum Field Theory II [Physics 253B] or Modern Atomic and Optical Physics I [Physics 285A] or Modern Atomic and Optical Physics II [Physics 285B] or Introduction to Quantum Theory of Solids [Physics 295A] or Quantum Theory of Solids [Physics 295B]
 and Advanced Quantum Mechanics II [Physics 251B]
 and Advanced Electromagnetism [Physics 232] or Modern Optics and Quantum Electronics [Applied Physics 216] or Optics and Photonics [Engineering Sciences/Applied Physics 273]
 and Statistical Physics [Physics 262] or Statistical Thermodynamics [Applied Physics 284].
Elective courses
Four additional halfcourses drawn from the following list, with at most two halfcourses in any one field. Note: not all courses listed are given every year, and course offerings, numbers, and contents sometimes change. Students therefore should occasionally confer with their advisors or with the chair of the Committee on Higher Degrees about their programs of study.

Other Fields:
A student may use 200level courses or fields not on this list with the approval of the Committee on Higher Degrees. In place of demonstrating proficiency by satisfactory course performance, a student may demonstrate proficiency by an oral examination, by submitting evidence of satisfactory work in appropriate courses taken at other institutions, or by other means deemed satisfactory by the Committee on Higher Degrees. Students wishing to utilize this option should submit a petition to the Committee on Higher Degrees before the end of their first year of Harvard graduate school. The general requirements outlined above are a minimum standard and students will usually take additional courses in their selected fields and in other fields. A student need not fulfill these requirements before beginning research. As a result of an exchange agreement between the universities, graduate students in physics at Harvard may also enroll in lecture courses at the Massachusetts Institute of Technology. The procedure is outlined under "CrossRegistration into Courses Offered by Other Faculties" in The Graduate School of Arts and Sciences Handbook.
Laboratory:
Adequate laboratory experience is a required part of the PhD program for all students who do not submit a thesis that demonstrates experimental proficiency. Students may satisfy this requirement in any one of the following ways:
 by taking the Laboratory Course in Contemporary Physics [Physics 247R],
 or by submitting documentation of equivalent laboratory experience,
 or by taking an oral examination on an experimental topic,
 or, for students planning on completing a thesis in a topic in astrophysics, by taking the Astrophysics Laboratory [Astronomy 191].
Students who wish to fulfill this requirement by equivalent laboratory experience, or by taking an oral examination, or by taking the Astronomy Laboratory should obtain approval of the Committee on Higher Degrees no later than the end of the third year of residence.
