Physics Changing my physics subfield between Master's and PhD

AI Thread Summary
The discussion centers on a master's student in physics who initially pursued Quantum Electrodynamics and experimental High Energy Physics (HEP) but shifted focus to other subfields, ultimately settling on space plasma physics for their thesis. The student now seeks to return to a PhD in Quantum Field Theory (QFT) or particle physics, questioning the feasibility of this transition. Responses affirm that it is realistic to switch back to these areas, emphasizing the importance of demonstrating the ability to learn, focus, and conduct independent research during a PhD. The conversation also highlights the significance of knowing the specific European country where the student is studying and plans to apply for their PhD, as this can influence the advice and opportunities available. The student confirms they are studying in Hungary.

Hello, dear all. Currently I'm studying MSc in physics hoping to do PhD soon after my graduation. I did my bachelor in Quantum Electrodynamics, and before starting my MSc in physics, I was working as a research assistant in experimental HEP lab, and I thought I wanted to explore other subfields in physics because I liked QFT theory more than experimental HEP at least I thought at the moment.

So my dislike of experimental HEP led me to explore other subfields of physics that are more practical etc. You see there was some escapist mentality. So finding another subfield that reignite my interest in physics was my sole goal. So I'm doing my master's as an explorative instrument to taste different fields, and by doing so I've taken many subfield subjects from biophysics, astrophysics, particle physics, condensed matter and so on. And I thought something related space is fruitful because of recent trends of Mars missions etc.

So I have been aimlessly wandering around till I decided to write my thesis on space plasma physics. This field is not that bad, but right after choosing my thesis I've finally accepted and embraced that I like the fundamental physics and I can spend rest of my life on particle physics/cosmology.

So my question is: is it possible/realistic for me to go back to PhD QFT/Particle physics, even experimental HEP from space plasma physics MSc?

Short answer: yes ! By all means.

So you want to make sure you get a PhD. It makes everything a lot easier. You have a broad interest which is good. For a PhD you have to prove you can a) learn new things b) focus to reach cutting edge and c) do independent research. From a PhD you get more options: you can continue in the same direction (often it takes twice as long as a PhD to actually be a specialist), or you can diversify in many ways: a little (from HEP to QFT or astrophysics or IT or nanotechnology, electronics, or whatever). Or diversify a lot (teaching, management, Greenpeace).

You don't have to like HEP to benefit from it! And it seems to me you are well equipped to flourish in some field. Don't stifle your options by planning too much.

OP: What country are you in now, and in what countries do you plan to apply for your PhD? From your Post #1, my guess is you're not in the US. I think the answer to your question will vary with the university system; so more info will lead to better answers.

Hello, I'm studying in an European country and planning to do my PhD here.

You'll get answers of better value if you identify which European country. From previous threads, there are certain policies applicable to multiple European countries, and certain policies specific to individual European countries. You want advice that is relevant to your specific instance.

It's Hungary
 
I don't know if anyone on here works for any of the well known defense companies of your country, whichever country you are from?? Also, if you choose to work in one, do you think the engineering education provide from your school would adequately prepare you for the job. What do I mean by that? Well if you work at say Lockheed Martin and you work in the latest iteration of a missile or if you work at Pratt & Whitney, they assign you to work in the team helping out with building the jet...
Hello, I graduated from undergrad a few years ago with a Major in Physics and minor in Electrical Engineering. I tried to get experience working on and testing circuits through my professor who studied Neutrinos, however covid caused the opportunity to go away and I graduated with no experience or internships. I have attempted to break into the engineering industry with no success. Right now I am considering going for a Masters in Electrical Engineering and I need advice on if this would be...
So lately, my interest in the realm of optics/optoelectronics/photonics engineering has grown and I have started to seriously consider pursuing a career in the field. I have done a bit of career research and also have done some learning on the side to gather more knowledge on these topics. However, I have some questions on what a career in these fields would look like, and I wanted to find out more about this area to know what I would be getting myself into if I did make the choice to pursue...
