Abstract:
We uncover a direct connection between three-dimensional gravity with chiral boundary conditions and a class of forced integrable systems. Starting from the Chern–Simons formulation, we derive consistent boundary conditions on a non-compact spatial slice, leading to boundary dynamics described by the potential modified KdV hierarchy. The dynamics reduce to a forced KdV equation, where the forcing term is determined self-consistently by the eigenfunctions of the associated Schr\”{o}dinger operator. Using the inverse scattering transform, the reflectionless sector is solved via the Gelfand–Levitan–Marchenko method, while the radiative sector exhibits universal dispersive decay.
This framework unifies AdS$_3$ boundary dynamics with integrable hierarchies and elucidates the roles of solitons and radiation in the dual conformal field theory.
About Speaker:
Hamed Adami is currently an Assistant Professor at SIMIS and Fudan University. He completed his PhD in Theoretical Physics at the University of Kurdistan in 2017. Prior to his current affiliation, he held postdoctoral positions at the School of Physics, Institute for Research in Fundamental Sciences (IPM, Tehran, Iran), at YMSC (Tsinghua), and BIMSA. His research mostly focuses on the holographic description of gravity, the fluid/gravity correspondence, and insights they might bring towards understanding the quantum properties of black holes.
