# Physics 230 A: Elementary Particle Theory

### Course Information for Fall 2017

Lectures:

- Time: Monday & Wednesday, 10:30 - 11:55
- Location: 469 Lauritsen

Office Hours:

- Time: to be determined
- Location: 452 Lauritsen

We will learn methods in quantum field theory which I hope are useful for theorists in high energy physics, condensed matter physics, quantum information, astrophysics, and cosmology. It is assumed that students have taken an introductory course on quantum field theory (such as Ph 205 at Caltech), which includes Feynman diagrams and renormalization in quantum electrodynamics (QED).

Plan (as of August 31, 2017; this may evolve in the next couple of weeks)

- Quantization of the Yang-Mills theory
- Spontaneously broken global and gauge symmetries
- Solitons and instantons
- Renormalization, renormalization group flow, and effective field theory
- Conformal field theory
