It’s all fun until we need to follow 2 research papers which uses different conventions simultaneously for reference. I had the worst experience yesterday while solving gravitational perturbations in schwarzschold metric.

Thanks a lot. Will try to follow this.

Can anyone recommend the order of books which I can follow for QFT? I already completed most of GR. I’m a beginner when it comes to QFT.Im reading Introduction to Elementary Particles by Grifiths rn. After that I’m planning to follow David tong’s lecture for QFT.

I found some chapters R Shankar helpful for theoritical understanding and I mainly followed JJ Sakurai for whole QM.
