伊戈尔·克列巴诺夫1962—

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.

Klebanov worked as a post-doc in the SLAC Theory Group.

His main contributions to string theory are in matrix model approaches, 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 anticipated the gauge theory-gravity correspondence.

Klebanov's 1998 paper, Gauge Theory Correlators from Non-Critical String Theory, with his graduate student Steven Gubser, and another Princeton Alexander M. Polyakov, made a precise statement of the AdS/CFT duality. It 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 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 has been called the Klebanov-Polyakov correspondence.

Klebanov's more recent work includes the Entanglement Entropy in confining gauge theories, the F-theorem for Renormalization Group flows, large N tensor models, field theory descriptions of critical phenomena, and quantum many-body scars as group invariant states.
