Igor R. Klebanov ((ロシア語:И́горь Романович Клеба́нов); 29 March 1962) is a theoretical physicist whose research is centered on relations between string theory and quantum gauge field theory. Since 1989, he has been a Professor at Princeton University where he is currently a Eugene Higgins Professor of Physics.〔http://www.princeton.edu/physics/people/display_person.xml?netid=klebanov&display=faculty/〕 Born in the Soviet Union in 1962, he emigrated to the U.S. as a teenager. He received his undergraduate education at MIT (class of 1982), and his Ph.D. degree at Princeton University as a student of Curtis Callan in 1986. In his thesis he made advances in the Skyrme model of hadrons. Klebanov worked as a post-doc at SLAC. His main contributions to string theory are in Matrix model approaches to two-dimensional strings, in brane dynamics, and more recently 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 Gubser, and Polyakov, which made a precise statement of the AdS/CFT duality, is among the all-time top cited papers in high-energy physics (it has over 7000 citations according to Google Scholar). 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 Ph.D. students include Akikazu Hashimoto, Steven Gubser, Christopher Herzog, Anatoly Dymarsky, Marcus Benna, Arvind Murugan, and Benjamin Safdi. He also co-advised David Lowe, Juan Maldacena, Daniel Baumann, and Silviu Pufu. ==Awards== *2010 Guggenheim Fellowship〔http://www.gf.org/fellows/16805-igor-klebanov〕 *2010 Princeton University Graduate Mentoring Award〔http://www.princeton.edu./main/news/archive/S27/43/89Q62/index.xml?section=topstories〕 *2014 Tomassoni Prize〔http://www.phys.uniroma1.it/fisica/archivionotizie/tomassoni-prize-2014〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Igor Klebanov」の詳細全文を読む スポンサード リンク
