Nathan "Nati" Seiberg (/ˈsaɪbɜːrɡ/; born September 22, 1956) is an Israeli American theoretical physicist who works on quantum field theory and string theory. He is currently a professor at the Institute for Advanced Study in Princeton, New Jersey, United States.

Honors and awards

He was recipient of a 1996 MacArthur Fellowship[1] and the Dannie Heineman Prize for Mathematical Physics in 1998.[2] In July 2012, he was an inaugural awardee of the Fundamental Physics Prize, the creation of physicist and internet entrepreneur, Yuri Milner.[3] In 2016, he was awarded the Dirac Medal of the ICTP. He is a Fellow of the American Academy of Arts and Sciences and a Member of the US National Academy of Sciences.

Research

His contributions include:

  • Ian Affleck, Michael Dine, and Seiberg explored nonperturbative effects in supersymmetric field theories.[4] This work demonstrated, for the first time, that nonperturbative effects in four-dimensional field theories do not respect the supersymmetry nonrenormalization theorems. This understanding led them to find four-dimensional models with dynamical supersymmetry breaking.
  • In a series of papers, Michael Dine and Seiberg explored various aspects of string theory. In particular, Dine, Ryan Rohm, Seiberg, and Edward Witten proposed a supersymmetry breaking mechanism based on gluino condensation,[5] Dine, Seiberg, and Witten showed that terms similar to Fayet-Iliopoulos D-terms arise in string theory,[6] and Dine, Seiberg, X. G. Wen, and Witten studied instantons on the string worldsheet.[7]
  • Gregory Moore and Seiberg studied Rational Conformal Field Theories. In the course of doing it, they invented modular tensor categories and described many of their properties.[8] They also explored the relation between Witten’s Topological Chern–Simons theory and the corresponding Rational Conformal Field Theory.[9] This body of work was later used in mathematics and in the study of topological phases of matter.
  • In the 90’s, Seiberg realized the significance of holomorphy as the underlying reason for the perturbative supersymmetry nonrenormalization theorems[10] and initiated a program to use it to find exact results in complicated field theories including several N=1 supersymmetric gauge theories in four dimension. These theories exhibit unexpected rich phenomena like confinement with and without chiral symmetry breaking and a new kind of electric-magnetic duality – Seiberg duality.[11] Kenneth Intriligator and Seiberg studied many more models and summarized the subject in lecture notes.[12] Later, Intriligator, Seiberg and David Shih used this understanding of the dynamics to present four-dimensional models with dynamical supersymmetry breaking in a metastable vacuum.[13]
  • Seiberg and Witten studied the dynamics of four-dimensional N=2 supersymmetric theories – Seiberg–Witten theory. They found exact expressions for several quantities of interest. These shed new light on interesting phenomena like confinement, chiral symmetry breaking, and electric-magnetic duality.[14] This insight was used by Witten to derive the Seiberg–Witten invariants. Later, Seiberg and Witten extended their work to the four-dimensional N=2 theory compactified to three dimensions.[15]
  • Intriligator and Seiberg found a new kind of duality in three-dimensional N=4 supersymmetric theories, which is reminiscent of the well-known 2D mirror symmetry – 3D mirror symmetry.[16]
  • In a series of papers with various collaborators, Seiberg studied many supersymmetric theories in three, four, five, and six dimensions. The three-dimensional N=2 supersymmetric theories[17] and their dualities were shown to be related to the four-dimensional N=1 theories.[18] And surprising five-dimensional theories with N=2 supersymmetries were discovered[19] and analyzed.[20]
  • As part of his work on the BFSS matrix model, Seiberg discovered little string theories.[21] These are limits of string theory without gravity that are not local quantum field theories.
  • Seiberg and Witten identified a particular low-energy limit (Seiberg-Witten limit) of theories containing open strings in which the dynamics becomes that of noncommutative quantum field theory – a field theory on a non-commutative geometry. They also presented a map (Seiberg-Witten map) between standard gauge theories and gauge theories on a noncommutative space.[22] Shiraz Minwalla, Mark Van Raamsdonk and Seiberg uncovered a surprising mixing between short-distance and long-distance phenomena in these field theories on a noncommutative space. Such mixing violates the standard picture of the renormalization group. They referred to this phenomenon as UV/IR mixing.[23]
  • Davide Gaiotto, Anton Kapustin, Seiberg, and Brian Willett introduced the notion of higher-form global symmetries and studied some of their properties and applications.[24]
