This section has my notes for various topics that I learnt through books and lectures. They are very terse and mostly intended for my own reference. Nevertheless, I am uploading my notes in the unlikely event that they are useful to someone.

• String theory notes: I am tring to work through Polchinski's two volume classic. These mostly contain details of calculations and my solutions to exercises.
• QFT-1: These notes were prepared from the QFT-1 course taught at ICTS-TIFR by Prof. Suvrat Raju.
• QFT-2: These notes were prepared from the QFT-2 course taught at ICTS-TIFR by Prof. Ashoke Sen.
