Education

  • 2018.08-2024.08, Ph.D. in Theoretical Physics, ICTS-TIFR, Bengaluru, India.
  • 2016.07-2018.07, M.S. in Physics, IIT Kharagpur.
  • 2013.09-2016.06, B.S. in Physics, Ramakrishna Mission Residential College Narendrapur.

Research Summary

Sarthak Duary studies flat-space holography, celestial amplitudes, string theory, and soft theorems, focusing on how gravitational scattering data can be reorganized into field-theoretic or worldsheet language. His recent work derives flat limits of AdS/CFT from AdS geodesics and develops celestial or Klein-space spectral representations, while related papers analyze soft scalar and photon theorems together with memory effects. Work on tensionless and tensile open strings in Kalb-Ramond backgrounds and on noncommutativity from covariant phase space connects the same flat-space questions to string-theoretic degrees of freedom.
