Where to study "Group Theory Physics"?

Click For Summary

Discussion Overview

The discussion centers on the applications of group theory in physics, particularly in the context of pursuing advanced studies such as a PhD. Participants explore the relevance of group theory across various fields within physics and mathematics, and the best academic paths for someone interested in this area.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant expresses a strong interest in group theory applications in physics and seeks advice on whether to pursue physics or math programs for a PhD.
  • Another participant suggests that if the focus is on understanding the laws of nature, a physics program may be more beneficial, as math departments may lack depth in physics applications.
  • A suggestion is made to explore theoretical particle physics as a relevant field for group theory applications.
  • Continuous symmetry operations are highlighted as a domain where physics has significant applications of group theory, with a recommendation for a specific book on the topic.
  • Group theory is noted to have applications in various fields, including condensed matter physics and even biophysics, although the relevance may vary.
  • Concerns are raised about the current state of the particle physics field, suggesting it may not be the best area to pursue at this time.

Areas of Agreement / Disagreement

Participants express differing views on the best academic path to take, with some advocating for physics programs while others suggest that group theory can be pursued effectively in math departments. There is no consensus on the optimal field of study or the current viability of particle physics as a career path.

Contextual Notes

Participants mention various applications of group theory, but the discussion does not resolve the specific contexts in which group theory is most beneficial or the current trends in related fields.

The field of physics I'm most interested in is group theory. I know it's technically a math subject, but I'm interested in using it in physics. So I guess you'd say "group theory applications in physics." I already have a Bachelor's in Engineering Physics from University of Oklahoma. I want to go for my PhD in this area. Should I be looking at physics or math programs? Any specific universities where this type of research is happening?
 
Physics news on Phys.org
I don't know a lot about the really deep applications of group theory (crystallography is one area), but if you are more interested in understanding the laws of nature than in doing math for math's sake, you should do physics, even if it means you end up not using much group theory. In math departments, there are only a few people who know physics well enough to have much more than a superficial relationship to real physics.
 
Look into theoretical particle physics.
 
When it come to continuous symmetry operations, physics dominates in applications. I'd recommend checking out a book called An Introduction to Tensors and Group Theory for Physicists by N Jeevanjee.

However, group theory finds application in many other places. Here's a computer science problem that was solved with group theory techniques: http://users.cms.caltech.edu/~umans/papers/CKSU05.pdf

Particle physics definitely has a huge variety of group theory applications. I wanted to add if you study any field of physics you will encounter group theory again.

I know some math guys that study group theory for physics applications (topological insulators) as well, but it's a different style of research. Different strokes for different folks
 
Now is a really dreadful time to be aiming at particle physics, the field seems to be continually shrinking. Condensed matter seems to involve some group theory if that's your cup of tea.

EDIT: That said you can find group theory applied practically anywhere but your mileage may vary. I saw a review paper a few months ago on applications of group theory to biophysics, which is not a subject anybody would expect to involve group theory.
