## Prof. A.W. Peet, T-HEP faculty

- Gravity is my favourite force in the Universe.
- Einstein's General Relativity is a v. successful theory of
*classical* gravitational fields, describing physics measured in experiments from microscopic scales all the way out to cosmological scales.
- But as a
*quantum* field theory, 4D GR is incomplete: it does not know how to handle ultra short distance/high energy phenomena.
- How much can we learn about Quantum Gravity? Black holes provide a fascinating theoretical laboratory for investigating this.

## What is the fabric of spacetime made of?

- Qualitatively new emergent phenomena can arise in physical systems in the limit of a large number of degrees of freedom. How does classical spacetime
*emerge* from Quantum Gravity?
- Focus: when do quantum effects come into play in systems with gravitational degrees of freedom, for as many different contexts as possible, e.g. in various dimensions, with black holes?

- Two fruitful toolsets I use:
- some aspects of String Theory, a promising approach to QG;
- Holography, which came from string theory but doesn't require it.

## Invitation to visit

**I am currently looking for one new grad student.** If you think you might be interested in what I work on, I encourage you to get in touch. I am not a scary monster and I don't bite! :D
- Suggested courses (in order of importance):-
- Quantum Field Theory x 2
- General Relativity x 2
- depending on undergrad background, some of: Statistical Mechanics, Introduction to HEP, Math Methods, Current Interpretations of QM, Entanglement Physics.
