3. Exploring relations between soft theorems – memory effect and black hole information – supertranslations using representations of BMS group.

Research Experience

1. HRI, Prayagraj, India
   • Post-Doctoral Fellow (Aug 2018 – 2020)
     • Thesis: Gravity from patterns in natural numbers
     • Research areas: Fundamental problem in physics is to quantify the structure of space-time and black hole information. This is popularly also known as quantum gravity. According to our hypothesis black hole is represented by partitions of natural numbers, in other words natural numbers are building blocks of nature. By studying merger of partitions we hope to recover Einstein’s equation. This will also have strong implications for artificial intelligence community.
