Symmetry, spacetime
& quantum matter.
I’m Arpit Das, a theoretical physicist studying how symmetry constrains quantum systems—from conformal field theories and entanglement to hydrodynamics and black holes.

01 / Research
Different questions.
A common thread.
My research connects the mathematical structure of quantum field theories with the physics of strongly interacting systems.
01
Holography & hydrodynamics
How do black holes encode the collective dynamics of quantum matter?
02Rational CFT & modular bootstrap
What can modular consistency tell us about possible conformal field theories?
03Generalized symmetries & entanglement
What structure becomes visible when entanglement is resolved into symmetry sectors?
04CFT on curved spacetime
How does background geometry constrain local quantum observables?
02 / Recent work
From the blackboard.

A little background.
I completed my PhD at Durham University with Nabil Iqbal and Ruth Gregory in 2023, followed by a postdoctoral position at the University of Edinburgh from 2023 to 2026. I am now based in Kolkata.
