**Primary Areas of Faculty Research:** Atomic and molecular physics; biophysics; condensed matter physics; laser physics; nanoscience; physics education; quantum optical physics; space and planetary sciences; surface physics; and theoretical physics.

**Prerequisites to M.S. and Ph.D. Degree Programs: **Prospective students must satisfy the requirements of the Graduate School as described in this catalog and have the approval of the Graduate Admissions Committee of the Department of Physics. In addition, to be admitted to graduate study in physics without deficiency, candidates should have an undergraduate degree with the equivalent of a 30-hour major in physics including intermediate-level courses in mechanics, electricity and magnetism, quantum physics and thermal physics, and mathematics through differential equations. Students who present less than the above may be admitted with deficiency dependent on degree track subject to the approval of the department’s Graduate Admissions Committee. Students may eliminate deficiencies while concurrently enrolling in graduate courses, provided prerequisites are met. While submission of Graduate Record Examination scores is not required for admission, students who have taken the GRE advanced physics test are urged to submit their test scores to the physics department to facilitate advising and placement.

## M.S. in Physics

**Requirements for the Master of Science Degree:** Students may choose between two Master of Science degrees in the physics department. These are the M.S. Physics (30-hour thesis path); and the M.S. Physics (36-hour non-thesis path). Both M.S. degree curricula prepare a student for the Physics Ph.D. degree.

Incoming graduate students will be advised by a departmental graduate adviser for the first two years. Students must form their thesis or advisory committees by the end of their third academic semester and file the appropriate forms with the Graduate School. The thesis committee (thesis-path students) consists of the research adviser as chair, two members of the physics faculty, and one member of the graduate faculty not from the Physics Department. The advisory committee (for non-thesis-path students) consists of the individual study project adviser as chair and two members of the physics faculty. Students in this degree program can choose either a 30-semester-hour thesis path or a 36-semester-hour non-thesis path.

Both the thesis and non-thesis M.S. degrees share the following academic requirements: Completion of:

PHYS 5011 | Introduction to Current Physics Research Seminar (Fa) | 1 |

PHYS 5073 | Mathematical Methods for Physics (Fa) | 3 |

PHYS 5413 | Quantum Mechanics I (Fa) | 3 |

PHYS 5313 | Advanced Electromagnetic Theory I (Fa) | 3 |

PHYS 5323 | Advanced Electromagnetic Theory II (Sp) | 3 |

PHYS 5111 | Research Techniques Through Laboratory Rotations (Sp) | 1 |

PHYS 5041 | Journal Club Seminar (Sp) | 1 |

Students who have had similar courses at another institution may substitute up to 12 credit hours of other courses in lieu of those listed above, on a course-by-course basis, upon petitioning the Graduate Affairs Committee.

Elective courses will be used for the remaining required degree hour. The minimum number of physics elective hours, the maximum number of non-physics technical elective hours, and the minimum number of total elective hours are shown in the table.

Degree | Physics Electives | Technical Electives | Total Electives |
---|---|---|---|

M.S. Physics Thesis | 9 | 0 | 9 |

M.S. Physics Non-Thesis | 18 | 0 | 18 |

Students will select electives from courses listed in the graduate catalog as appropriate to their field of specialization, with course selection approved by their thesis committee. For the purposes of this degree requirement, any Astronomy (ASTR) graduate course listed in the Graduate Catalog and taught through the physics department will be considered a Physics elective.

No more than one 4000-level course may be counted toward the 30-hour requirement for the thesis option, and no more than two 4000-level courses may be counted toward the 36-hour requirement for the non-thesis option.

**Requirements for Thesis-Path M.S. Degrees:** Completion of six master’s thesis hours under PHYS 600V and a written thesis successfully defended in a comprehensive oral exam given by the student’s thesis committee.

**Requirements for Non-thesis Path M.S. Degrees:** Completion of three hours under PHYS 502V Individual Study in Advanced Physics and a written project report successfully defended in a comprehensive oral exam given by the student’s advisory committee. Students who pass the Physics Ph.D. candidacy examination will be considered to have satisfied the PHYS 502V requirement of the non-thesis path M.S. degrees.

Students should also be aware of Graduate School requirements with regard to master's degrees.

## Ph.D. in Physics

**Requirements for the Doctor of Philosophy Degree:** To be admitted to candidacy for the Ph.D. degree the student must a) form a dissertation committee; b) pass the candidacy exam, c) obtain a minimum of B-grade in core physics courses and d) file a Declaration of Intent with the Graduate School.

Incoming graduate students will be advised by a departmental adviser for the first two years. Students must form their dissertation committees by the end of their third academic semester and file the appropriate forms with the Graduate School. The dissertation committee consists of the research adviser as chair, three members of the Physics faculty, and one member of the graduate faculty not from the Physics Department.

The candidacy examination covers three areas: Quantum mechanics, electromagnetism, and classical mechanics, all at the graduate level, although questions at the undergraduate level may also be asked. The exam is given on three days in the week preceding the start of the Spring semester classes. Students entering the graduate program in the Fall semester will take the exam no later than after three semesters of graduate study at the University of Arkansas, and those entering the graduate program in the Spring semester will take it no later than after the fourth semester of graduate study. A passing grade of 55 percent in each area will be required. The students will be allowed a second and final attempt in the failed areas the following year. In the exceptional cases where after the second attempt, the student has failed only one area and his/her score in that area is not below 50 percent, the faculty may allow a third attempt or an oral exam. This exam will be given within six weeks after the second attempt.

Ph.D. students must complete a minimum of 40 semester-hours in 5000- and/or 6000-level courses beyond their Bachelor of Science degrees. Courses taken to fulfill the requirements for the University of Arkansas M.S. physics degrees can be included in this 40 semester-hour requirement. Students who have had similar courses as part of an M.S. physics program at another institution may obtain a waiver for up to 21 credit hours, on a course-by-course basis, upon petitioning to the Graduate Affairs Committee.

Ph.D. students must take:

PHYS 5011 | Introduction to Current Physics Research Seminar (Fa) | 1 |

PHYS 5103 | Advanced Mechanics (Fa) | 3 |

PHYS 5263L | Experiment and Data Analysis (Sp) | 3 |

If a minimum grade of B is not obtained, the course may be repeated once. If the student cannot obtain a minimum of B on two attempts, he/she will not be allowed to continue in the Ph.D. program.

Thirteen additional hours in elective physics graduate courses will be required, and they must be selected from the 5000- or 6000-level courses listed in the graduate catalog appropriate to the student’s field of specialization and approved by the student’s advisory committee. For the purposes of this degree requirement, any Astronomy (ASTR) graduate course listed in the Graduate Catalog and taught through the physics department will be considered a physics elective. Additional elective courses outside of the physics department may be taken with dissertation committee approval.

Ph.D. students must also earn 18 hours of credit in Doctoral Dissertation, submit a dissertation, and defend it successfully in a comprehensive oral examination given by the dissertation committee.

Students should also be aware of Graduate School requirements with regard to doctoral degrees.
