I'm starting my master in physics, and it's time for me to choose my courses.

I will take one or two of the following three courses, which are: Statistical Physics, QFT and General relativity.

Now, I'm finding it very hard to decide as on the one hand, I'm interested in QFT and General relativity. I can also not imagine a physics phd that has never heard about QFT and General relativity?

On the other hand, statistical phyiscs seems to be quite important for most research areas. Especially if I'm not planning to go into the field of particle physics. Is that correct? Or am I completely fine in most phd programs if I never heard a course in stat physics?

Now I've already done some StatMech in my Bachelors degree, but definitely not as advanced as will be treated here. I know about Fermi Dirac and Bose Einstein, and the different canonical ensembles, but that's about it.As for the actual contents of the courses:

Statistical Physics

Basics of kinetic gas theory: conservation laws, H-theorem, Boltzmann-Equations, Maxwell distribution.

Classical statistical physics: microcanonical ensembles, canonical ensembles and grandcanonical ensembles, applications to simple systems.

Quantum statistical physics: single particle, ideal quantum gases, fermions and bosons.

Bose-Einstein condensation: Bogolyubov theory, superfluidity.

Mean field and Landau theory: Ising model, Heisenberg model, Landau theory of phase transitions, fluctuations.

Critical phenomena: mean field, series expansions, scaling behavior, universality.

Renormalization group: fixed points, simple models.

Linear response theory: general formulation, response in mean field, sum rules, collective modes, fluctuation dissipation theorem.

QFT I:

Topics include:

- Relativistic quantum mechanics

- Quantisation of bosonic and fermionic fields

- Interactions in perturbation theory

- Scattering processes and decays

- Radiative corrections

I can realistically take like one or two of the three courses. I might also be able to take the other course a year from now, although I'm not sure if that'll work out. If I left out anything important, please let me know!
