# Graduate Courses

#### First Year

Each graduate student selects a course of study in consultation with a graduate adviser. A student with weaknesses in preparation may be advised to take one or more advanced undergraduate courses the first year. Otherwise, students are normally expected to take a sequence of "core courses" in classical mechanics, electrodynamics, quantum mechanics, mathematical methods, and statistical mechanics. Students with advanced preparation can often get permission to skip a core course, but this requires approval by a departmental committee.

First year students are also expected to sign up for the Colloquium (PHY 290), in which outside speakers give broad overviews of topics of current research. Winter quarter, students also enroll in a course on departmental research (PHY 295), in which faculty members give introductions to their research areas. This course is especially useful for students who are trying to pick out a specialization and a Ph.D. adviser. Throughout their time at Davis, students may also sign up for a "Career Options" seminar (PHY 285) that brings in speakers from outside academia and occasionally arranges field trips to Silicon Valley.

By the second or third quarter, students are encouraged to spend a portion of their time on research, usually in the form of one or two units of Physics 299 under the direction of a faculty member. This does not commit a student to a given adviser or research area, but is often helpful in making such a choice later on. Quite often, this research has led to a thesis and has greatly accelerated its completion.

A typical first year graduate program for a Ph.D. student with a teaching assistantship and with no deficiencies in undergraduate preparation would be:

Fall Quarter | Winter Quarter | Spring Quarter |

Physics 200A | Physics 200B | Physics 200C |

Physics 204A | Physics 204B | Physics 215C or 230A |

Physics 215A | Physics 215B | Physics 219A |

Physics 290 | Physics 290 | Physics 290 |

Physics 390* | Physics 295 | (Physics 299) |

Physics 396* | (Physics 299) | Physics 390* |

Physics 390* | Physics 396* | |

Physics 396* |

* If Teaching Assistant for a lab.

#### Second Year

After the first year of general courses, graduate students are normally expected to choose an area of specialization. Second year students take a sequence of specialized "cluster courses" in their fields. The present clusters are:

- Condensed Matter Experiment: PHY 240ABC
- Condensed Matter Theory: PHY 219B, 240ABC
- High Energy Experiment: 230AB, 245ABC, 252B
- High Energy Theory: 230ABC, 245ABC, 246, 252B
- Nuclear Physics: PHY 230A, 252B, and three courses from 224ABC and 229AB
- Biophotonics Designated Emphasis (Experiment): PHY 240AB; EAD 271; BIS 101 or 102 or 104 or BIM 202
- Biophotonics Designated Emphasis (Theory): PHY 219B, 240AB; EAD 271; BIS 101 or 102 or 104 or BIM 202
- Observational Cosmology: PHY 265, 266, 267
- Theoretical Cosmology: PHY 230AB, 260, 262, 263

Second year students also typically sign up for a seminar (PHY 291, 292, 293, or 294), in which outside speakers give talks in particular areas. By this time, students should also begin serious work on independent research (PHY 299). A typical second year schedule would be:

Fall Quarter | Winter Quarter | Spring Quarter |

Physics 290 | Physics 290 | Physics 290 |

Physics 291,2,3 or 4 | Physics 291,2,3 or 4 | Physics 291,2,3 or 4 |

Physics 299 | Physics 299 | Physics 299 |

Physics 390* | Physics 390* | Physics 390* |

Physics 396* | Physics 396* | Physics 396* |
