Anton Kapustin

Anton Kapustin is a theoretical physicist noted for contributions to quantum field theory, string theory, and topological phases of matter. He has worked at notable institutions including Princeton University, Harvard University, and California Institute of Technology, and has collaborated with researchers affiliated with Perimeter Institute for Theoretical Physics and Stanford University. His research bridges concepts from Edward Witten's work on supersymmetry and ideas from condensed matter research in Xiao-Gang Wen's tradition.

Early life and education

Kapustin was educated in Russia at Moscow State University where he studied under faculty linked to Soviet-era theoretical physics traditions and later moved to the United States for doctoral studies at Princeton University. At Princeton University he worked in the milieu shaped by Edward Witten, Alexander Polyakov, and faculty associated with the development of modern quantum field theory and string theory. During his graduate training he interacted with peers from institutions such as Harvard University, Yale University, Columbia University, New York University, and research centers like Institute for Advanced Study and CERN. His early academic network included collaborations with researchers from Stanford University, University of California, Berkeley, and Massachusetts Institute of Technology.

Academic career and appointments

Kapustin held postdoctoral and faculty positions at major research centers, including a postdoctoral appointment at Princeton University and faculty appointments at Harvard University and later at California Institute of Technology. He has been a visiting scholar at institutes such as Perimeter Institute for Theoretical Physics, Institute for Advanced Study, and CERN. His teaching and mentorship connected him with graduate programs at Stanford University, University of Chicago, Columbia University, and summer schools like those organized by Kavli Institute for Theoretical Physics and ICTP. He has served on scientific advisory panels for organizations such as Simons Foundation, National Science Foundation, and research collaborations involving Microsoft Research and IBM Research.

Research contributions and notable work

Kapustin's work advanced the understanding of topological quantum field theory through studies that connect supersymmetry-based techniques to topological phases studied by Xiao-Gang Wen and condensed matter theorists from Bell Labs and Rutgers University. He produced influential results on dualities in three-dimensional gauge theory that relate to concepts originally developed by Seiberg and E. Witten and intersect with the AdS/CFT correspondence as formulated by Juan Maldacena and explored by researchers at Perimeter Institute for Theoretical Physics. His papers on symmetry-protected topological phases echo themes from Frank Wilczek's and Robert Laughlin's work and interface with experimental efforts at Bell Labs and Harvard University's Center for Ultracold Atoms.

Kapustin formulated field-theoretic descriptions of topological orders that influenced both mathematical physics and condensed matter communities, drawing on tools from category theory as used by mathematicians at Institute for Advanced Study and techniques from algebraic topology rooted in the traditions of Michael Atiyah and Graeme Segal. His collaborations bridged groups at Princeton University, California Institute of Technology, and Perimeter Institute for Theoretical Physics, and his work connects to efforts by researchers at Microsoft Research on topological quantum computation inspired by Alexei Kitaev and Serguei Bravyi. He also contributed to the theoretical foundations underpinning studies at experimental facilities such as Argonne National Laboratory and IBM Research.

Awards and honors

Kapustin's contributions have been recognized by scholarly communities with invitations to major conferences including Strings Conference, Solvay Conference, and lectures at Institute for Advanced Study. He has received research support from funding bodies such as National Science Foundation and philanthropic organizations including Simons Foundation. He has been an invited speaker at venues like International Congress on Mathematical Physics and awarded honors from university departments at Harvard University and California Institute of Technology.
