Igor R. Klebanov (born 1962) is an American theoretical physicist. Since 1989, he has been a faculty member at Princeton University, where he is currently a Eugene Higgins Professor of Physics and the director of the Princeton Center for Theoretical Science. [1] In 2016, he was elected to the National Academy of Sciences. [2] Since 2022, he is the director of the Simons Collaboration on Confinement and QCD Strings. [3]

Klebanov received his undergraduate education at the Massachusetts Institute of Technology, class of 1982, and his Ph.D. degree at Princeton University in 1986 as a student of Curtis Callan. In his thesis he made advances in the Skyrme model of hadrons, which included the first paper on a Skyrmion crystal. [4] Klebanov worked as a post-doc in the SLAC Theory Group. His main contributions to string theory are in matrix model approaches to two-dimensional strings, in brane dynamics, and in the gauge theory-gravity duality. His work in 1996-97 on relations between branes in supergravity and their gauge theory description [5] anticipated the gauge theory-gravity correspondence.
Klebanov's 1998 paper [6] with his graduate student Steven Gubser, and Alexander M. Polyakov, which made a precise statement of the AdS/CFT duality, is among the top cited papers in theoretical high-energy physics. A series of papers by Klebanov and collaborators on D-branes on the conifold has led to discovery [7] of cascading gauge theory. Its dual warped throat provides a geometric description of color confinement and chiral symmetry breaking; it has been used in model building for cosmology and particle physics. The relation between 3-dimensional critical O(N) model and bosonic higher-spin gauge theory in 4-dimensional AdS space [8] has been called the Klebanov-Polyakov correspondence.
Klebanov's more recent work includes the Entanglement Entropy in confining gauge theories, [9] the F-theorem for Renormalization Group flows, [10] large N tensor models, [11] field theory descriptions of critical phenomena, and quantum many-body scars as group invariant states. [12]
