General Relativity and Quantum field theory

Click For Summary

Discussion Overview

The discussion centers around the pursuit of doctoral studies in General Relativity and Quantum Field Theory, with a focus on potential universities and the viability of entering these specialized fields. Participants share insights on academic opportunities, challenges in the field, and specific institutions known for their work in theoretical physics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant expresses interest in pursuing a doctoral program abroad, specifically mentioning a university in Canterbury, New Zealand, and seeks advice on its reputation for theoretical physics.
  • Another participant warns against entering gravitation physics, citing it as overcrowded and divisive, and suggests exploring information theory instead.
  • A participant notes that while General Relativity and Quantum Field Theory receive significant attention, very few physicists work in these areas full-time, with most focusing on solid-state physics.
  • Some participants highlight that David Wiltshire at Canterbury is a notable figure in quantum gravity, while others mention Matt Visser at Victoria University of Wellington as a key researcher in General Relativity and Quantum Field Theory.
  • One participant emphasizes the quality of Visser's work and suggests that his papers are well-written and valuable for understanding theoretical gravitation physics.
  • The original poster expresses concern about their chances of entering this specialized field and asks about the factors that influence admission into doctoral programs.
  • A participant shares observations about the limited interest and resources for studying General Relativity and Quantum Mechanics in Syria, noting that many graduates end up teaching rather than pursuing research.

Areas of Agreement / Disagreement

Participants generally do not reach a consensus on the advisability of pursuing a career in gravitation physics, with some cautioning against it due to perceived challenges, while others highlight specific researchers and institutions that may offer valuable opportunities.

Contextual Notes

There are varying opinions on the accessibility of doctoral programs in specialized fields, and participants acknowledge the competitive nature of these areas without resolving the uncertainties surrounding them.

Since I'm very interested in General Relativity and Quantum field theory, I'd like to start a doctoral program abroad after my master study (I'm studying in Switzerland and will get my master degree in approximately 1.5 years).

I was surfing around in the internet and found for example the university in Canterbury in Newzeeland. Is this an advisable university for theoretical physics?
Or does anyone know a physics department which is specialized in General Relativity and Quantum field theory?
 
Physics news on Phys.org
Don't do it!

Gravitation physics is overcrowded and divisive. People I know who worked in that field have mostly left it, for some pretty good reasons. (Hmm... Canterbury... did you hear a different take from Roy Kerr, then?)

What about information theory? See https://www.physicsforums.com/showthread.php?t=183900

I hope you realize that it is a VERY specialized field. While GR, quantum field theory etc tend to get a lot of publicity in popular science the reality is that very few physicists actually work in these field; there are probably only a few hundred in the whole world that work on GR, string theory etc full time.
The vast majority of all physicists work in solid-state physics and related fields; and even then it is difficult to find academic positions.
 
Ditto f95toli, and good point. "Overcrowded" means "overcrowded puddle" compared to the sea of solid state physics :wink:
 
David Wiltshire (Canterbury) is really the only person in New Zealand who works on quantum gravity.

You might be able to hunt down some more prospective supervisors by looking at
http://en.wikipedia.org/wiki/List_of_loop_quantum_gravity_researchers

And you might also look for organizations for physicists in this specialty.

Since you are doing your master's, you might get good advice from your current supervisor and his/her PhD students.
 
At Victoria University of Wellington, Matt Visser works on general relativity, quantum field theory, and cosmolgy.

My statement stands amended!
 
New Zealand: Center of the Universe (of Gravitational Physics)

Matt Visser is in fact IMO almost* the only person who (with students and coworkers) is currently doing useful work in theoretical gravitation physics. (Apart from the odd contribution in classical relativity.)

Note to OP: Visser's papers are among the best in part because they are well written, so go ahead and look some up even though (I presume) you currently lack the background to fully appreciate them. I happen to enjoy solving PDEs, so I like his papers on ssspfs (static spherically symmetric perfect fluid solutions), but his most important work is probably this stuff: http://relativity.livingreviews.org/Articles/lrr-2005-12/index.html If it ever becomes possible to experimentally verify an analogue of Hawking radiation, this would surely result in a Nobel Prize. And it has nothing to do with string theory or gtr. Rather, any other reasonable gravitation theory must of course obey the laws of thermodynamics. But while this principle seems reasonable, it must be checked ASAP.

*Ted Jacobson also comes to mind. (Before you ask, unless I have misunderstood something, John Baez no longer works directly in gravitation physics. But he has a PF account https://www.physicsforums.com/showthread.php?t=173713 so I should really let him speak for himself.)

Thank you for your advices!

I really don't want to do some kind of pop science, I'm more interested in the theoretical physics of General Relativity and Quantum field theory. So, I think (after reading your tips) New Zealand, Canada or UK would be the best.
I already know it's hard to find an open position for doing a doctoral program, especially when you haven't studied at a university with a very good reputation.

So, do you think, I have a real chance to get into this very specialized field? On which factors does it depend?

there's a lot of physics students in Syria havnt ever heard about
General Relativity and Quantum Mecanis Applications...
just a few peple are intersted in QT and GR in Syria
in fact...most physicians after the graduate are teaching physics
for students in schools...
Unfortunately, physical researches are limite here...
