Have we found all string theories?
This brief post answers the question, “Have we found all string theories?”. It will require a basic understanding of QFT and symmetry algebras.

String Theory and M theory compactifications
This is a post about compactifications in superstring theory and M theory. This post is related to my second Ph.D. project. A little familiarity with the Ricci tensor and the word “gauge group” is assumed but I tried to make it self-contained.

Polchinski Volume 1 review
This is a chapter-by-chapter review of volume 1 of Polchinski’s book on string theory.

Gauge groups in bosonic and Type I string theories
A small post about how the cancellation of anamolies determine the unique gauge group that arises in bosonic and Type I string theories.

D Branes in Type II string theories
Let’s do a small post on D-Branes and their charges. Before starting, we will review some familiar concepts so that it is easy to understand what follows. A very basic understanding of electromagnetism and Quantum Field Theory (QFT) is assumed.

Heterotic String Theories explained
Why do we have two heterotic theories i.e. SO(32) heterotic and E8 X E8 heterotic? How do we come to this conclusion? I will present some results without derivation because their derivation requires calculations. A very basic understanding of quantum field theory is assumed and it is better if the reader has already read my…

On attending talks
(Please keep in mind that since I am a Physics student, some of my examples will be more relevant to Physics and Mathematics but most of the things discussed here apply to arbitrary fields of study). There is something, about which I don’t have a strong opinion, although I want to have a strong opinion…
