CHEP started a Ph.D. programme from the academic year 1996-97. The minimum qualification for applying is an M.Sc. in Physics, Mathematics or Chemistry, or a B.E./B.Tech. degree.

The programme is oriented towards research in theoretical and experimental high energy physics as well as mathematical physics. General research areas include: quantum field theory, the standard model of particle physics and beyond, new particle searches, collider data analysis, detector physics and fabrication, QCD and lattice gauge theories, quantum gravity, string theory and black holes, non-commutative geometry, quantum computation, condensed matter systems in low dimensions. The research interests of individual faculty members can be found in their respective home pages under Personnel.

The advertisement, examination, interview procedure, etc. are part of the overall procedure followed by IISc. The interviews for the CHEP programme are conducted by a departmental committee.

After admission, basic knowledge of the incoming students in the following subjects is checked: Classical mechanics, Electromagnetic theory, Mathematical physics, Quantum mechanics, Thermodynamics and statistical physics. During the first year, students are expected to fill up gaps in their knowledge, if necessary by solving a set of problems on the subjects.

Course requirements: First semester | Second semester ---------------- | ----------------- Quantum Mechanics III 3:0 | Advanced Mathematical 3:0 Quantum Field Theory I 3:0 | Methods in Physics Elective E1 (One) 3:0 | Elective E2 (One or Two) 3:0/6:0 ----- | --------- 9 | 6/9 ----- | --------- Third semester | ---------------- | Elective E3 (One or None) 3:0/0 | ----- | 3/0 |The minimum course credit requirement for the IISc Ph.D. programme is 18. The total course credit requirement for CHEP is higher---the list above ranges from 18 to 21 credits (because of the extra electives).

Electives (some electives may not be offered every year): E1: Nuclear and Particle Physics (3:0), Advanced Statistical Physics (3:0), Condensed Matter Physics II (3:0). E2: Quantum Field Theory II (3:0), General Relativity (3:0), Quantum Statistical Field Theory (3:0), Quantum Computation (3:0), String Theory (3:0), Experimental High Energy Physics (3:0). E3: The Standard Model of Particle Physics (3:0), String Theory II (3:0), QCD and Collider Physics (3:0). All the electives may not be offered every year. The students have to choose the electives in consultation with their supervisors. The supervisor may ask the students to take more electives than the list above, even after the Comprehensive Exam, as per his/her needs and interests.

There is no provision for skipping courses, but a student may seek exemption from any course by passing a written test at the beginning of the term.

Some of the courses overlap with those of the Physics department. The CHEP specific courses are: Nuclear and Particle Physics, Quantum Mechanics III, Quantum Field Theory I and II, Advanced Mathematical Physics, General Relativity, Quantum Computation, String Theory and II, The Standard Model of Particle Physics, Experimental High Energy Physics, and Collider Physics. The syllabi for these courses appear below.

There will be a Comprehensive Exam, which the students must take as soon as possible after passing the above courses. In any case, they must take the exam before the end of their second year. The exam will test whether the student has sufficient preparation to begin Ph.D. research. Those who fail the exam will be given another attempt after a few months.

At the time of joining, each student must find a provisional Faculty Advisor, who may not turn out to be the actual Ph.D. supervisor. The student must select the Ph.D. supervisor by the end of the second semester. Students will be permitted to work with a faculty outside CHEP if their research interests so demand. In such cases, however, they must have a joint supervisor in CHEP.

Beginning from the second year, students must present a seminar each year on their work, to acquaint the CHEP faculty with their progress.
