Switching from High Energy Physics to condensed matter theory

[Sil3nt]

Hello,

I am a master student, currently starting a master thesis on plasma astrophysics after a master focused on high energy theory (lots of QFT and particle physics, with some supersymmetry, string theory...).
I already have funding to continue my master thesis as a PhD, but I am getting interested in condensed matter theory, and I am thinking of returning to my university for another semester or two (which would make me finish my master's in 2.5-3years instead of 2) to take some classes in solid state, and see if I can do my PhD in that field. I am also a bit anxious about continuing into astrophysics, as the prospects in that field are not great...
Unfortuneatly I didn't do much condensed matter before, so I doubt a professor would take me as a PhD student right now, but on the other hand I am afraid that taking an extra year to do something completely different will look horrible on my CV, and the worst thing that could happen is finding myself 1 year from now with 0 phd positions after a 3year masters...
Any advice?

The best advice I can give is to speak to your advisor or another professor at your university who specializes in condensed matter theory. They will be able to provide you with the best advice based on your specific situation and experience. It is important to consider all options before making a decision, so it might also be helpful to talk to other students who have gone through similar experiences to get a better understanding of what you could expect. Additionally, you should research the job market for both fields to determine which would be the most suitable for you. That way, you can make an informed decision on where to focus your efforts.
