IIT Guwahati // Curious Explorer

I am an MSc graduate in Physics from IIT Guwahati, and quantum gravity is not a research interest for me. It is an obsession. What gravity is at the quantum level, how spacetime encodes information, why holography works at all. These are the questions that claimed me before I had the tools to answer them, and that gap is what has driven everything since.

I started reading Polchinski as a first-year undergraduate. Not because anyone asked me to. I needed to know what was at the bottom. I have spent years with string theory and conformal field theory, working through calculations that most treatments omit. My CFT notes contain derivations I could not find written down anywhere.

That long exploration made my research interests wide. I now work at the intersection of inflationary cosmology, reheating dynamics, and quantum field theory in curved spacetime. I arrived here because the questions I care about most eventually forced me to take the early universe seriously. It is the only laboratory we have for quantum gravity at accessible energy scales. Every area I have gone deep into exists for one reason: to come at the hard problems from more directions than one.

I maintain detailed public notes because I want these subjects to be accessible to everyone. If something as complex as string theory can be broken down in terms of calculus and algebra, then the barrier is not intelligence. It never was. Anyone willing to do the work can wonder about these things. That matters to me more than anything else on this page.

Research Interests

Holography

Investigation into the unitary evaporation of black holes, holographic duality, and entanglement entropy calculations using the replica trick.

$$S = \text{min}_{\gamma_A} \left[ \frac{\text{Area}(\gamma_A)}{4G_N} \right]$$

Gravity & QFT

Analyzing inflation/reheating dynamics and quantum field theory in curved spacetime.

$$\hat{G}_{\mu\nu} + \Lambda \hat{g}_{\mu\nu} = 8\pi G \langle T_{\mu\nu}\rangle$$
