main.pdfThis is a slide presentation for my project done in the 7th semester at IISER, Pune. I read and understood the seminal paper on 2D CFT's by Belavin, Polyakov and Zamolodchikov.
I encourage all of you to read and digest this seminal paper by BPZ :www.sciencedirect.com/science/article/pii/055032138490052X
Chaos, Butterfly effect and Holography.pdfThis is a Project I completed during my 8th semester at IISER, Pune. The objective of the project was to understand the idea of Chaos in QFT, eventually leading upto the Chaos Bound paper by D.Stanford, J. Maldacena and S. Shenker.
Resource: I suggest a set of three papers :
Presentation_paper.pdfThis is a slide presentation for my mid-year MS thesis project, done at Tata Institute of Fundamental Research, Mumbai. Here, we try to classify all local(analytic) four-photon and four-graviton S-matrices. We also put forward a conjecture, called the Classical Regge Growth Conjecture, assuming which we show that Einstein gravity is the unique classical classical gravitational theory for spacetime dimensions less than or equal to six, provided the exchanges is bounded in spin.
This work resulted in a research paper: https://arxiv.org/abs/1910.14392
In my 5th semester, I did a reading project with Dr. Nabamita Banerjee(now at IISER Bhopal) on QFT in curved spacetimes. This project introduced me to ideas which appeared radically different from the notion of QFT in flat spacetime. At the first stage itself, to realize that the notion of a particle itself is observer dependent is quite a surprise for a student. I had been fascinated by the information paradox and the idea of Black Holes since high school, but it was because of this project that for the first time, I was able to appreciate the Information Paradox in a technical manner.

During my 6th semester, I did a reading project with Dr. Sunil Mukhi at IISER, Pune on Asymptotic symmetries and it's relation to the Soft Theorems. This was quite interesting since one of my long term goals is to understand and explore the information paradox in more detail. At the beginning of my sixth semester, I stumbled across some papers by Strominger, Hawking and Perry which was interesting to me as it appeared to be a progress towards solving Information Paradox. This inspired me to study the 'IR triangle' more closely.
