Lee, Sangmin
Professor
String theory, Quantum field theory, General relativity
Sangmin Lee works on string theory, quantum field theory and general relativity. His early work includes the fuzzy 4-sphere D-brane solution in string theory and the 3-point correlation function in the AdS5/CFT4 correspondence. He led collaborations which proposed a large family of supersymmetric gauge theories in two and three spacetime dimensions corresponding to Calabi-Yau 4-fold conical singularities. He constructed the Grassmannian integral formula for scattering amplitudes of the ABJM theory. Since 2018, he has been involved in applying amplitude techniques to post-Mikowskian gravity relevant for gravitational wave physics. In particular, his group proposed a novel twistor-based model for spinning compact bodies such as Kerr black holes.
