# Graduate Program

#### Graduate Opportunities

The Fields, Strings, and Gravity group, as well as other areas of theoretical and mathematical physics (covered in the QMAP center), will potentially be taking on students each year. However, a pre-requisite is that you have to be admitted by the physics departments, satisfy various course and progression requirements, as well as requirements individual faculty may have for taking on students (eg. a trial project).

Please consult the Physics graduate pages for application information.

#### Background & Pre-requisites

The group expects students to be familiar with the workings of Quantum Field Theory, Gravity, and elements of String Theory. The former two topics are covered under the current Physics department courses PHY 230A, 230B, 230C, and 260, respectively.

There will be in due course, designated FSG courses, but for the present the courses will be taught as special topics (PHY 250). We expect that in the upcoming academic years we will offer two courses:

- Physics 232: Topics in String Theory
- Physics 233: Topics in Geometry and Physics

The offerings for the past couple of years are detailed below.

## FSG Graduate Courses

### Academic year 2020-2021

##### 1. Topics in String Theory (Winter 2022): The AdS/CFT correspondence (Mukund Rangamani)

The course will introduce the basic ideas behind the AdS/CFT correspondence and describe various applications. Topics to be covered include, large N field theories, motivation for the correspondence from D-brane dynamics, and developing the basic dictionary between the CFT and gravitational dynamics in AdS spacetimes (correlation functions, Wilson loops, entanglement entropy, etc). The second half of the course will focus on applications of the correspondence to understanding QCD dynamics (AdS/QCD), phases of compressible phases of matter (AdS/CMT), hydrodynamics (fluid/gravity), and the physics of black holes and quantum gravity (bulk reconstruction via entanglement).

**Pre-requisite****:** basic knowledge of quantum field theory (PHY 230A and B or equivalent) and general relativity and black holes (PHY 260 or equivalent)

##### 2. Advanced topics in Geometry & Physics (Winter 2022): Global aspects of spacetimes (Veronika Hubeny)

The course will cover classic results on global structures of spacetimes, singularity theorems in classical general relativity in the first part of the course. The second part will focus on developments related to the generalized second law, quantum focussing conjectures, and recent proofs of energy theorems for quantum fields in curved spacetime.
