Honors and awards edit
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 Breakthrough Prize in Fundamental Physics, 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 edit
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]
