Igor Klebanov
Igor R. Klebanov (Russian: И́горь Ромáнович Клеба́нов; Ukrainian: Ігор Романович Клєбанов; born March 29, 1962) is an American theoretical physicist.He received his undergraduate education at MIT (class of 1982) and his Ph.D. degree at Princeton University in 1986 as a student of Curtis Callan.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.
