Argyres-Seiberg duality and the Higgs branch
Davide Gaiotto, Andrew Neitzke, Yuji Tachikawa
We demonstrate the agreement between the Higgs branches of two N=2 theories proposed by Argyres and Seiberg to be S-dual, namely the SU(3) gauge theory with six quarks, and the SU(…
S-Duality of Boundary Conditions In N=4 Super Yang-Mills Theory
Davide Gaiotto, Edward Witten
By analyzing brane configurations in detail, and extracting general lessons, we develop methods for analyzing S-duality of supersymmetric boundary conditions in N=4 super Yang-Mill…
Four-dimensional wall-crossing via three-dimensional field theory
Davide Gaiotto, Gregory W. Moore, Andrew Neitzke
We give a physical explanation of the Kontsevich-Soibelman wall-crossing formula for the BPS spectrum in Seiberg-Witten theories. In the process we give an exact description of the…
Spin Chains in N=6 Superconformal Chern-Simons-Matter Theory
Davide Gaiotto, Simone Giombi, Xi Yin
In this note we study spin chain operators in the N=6 Chern-Simons-matter theory recently proposed by Aharony, Bergman, Jafferis and Maldacena to be dual to type IIA string theory…
Janus Configurations, Chern-Simons Couplings, And The Theta-Angle in N=4 Super Yang-Mills Theory
Davide Gaiotto, Edward Witten
We generalize the half-BPS Janus configuration of four-dimensional N=4 super Yang-Mills theory to allow the theta-angle, as well as the gauge coupling, to vary with position. We sh…
Supersymmetric Boundary Conditions in N=4 Super Yang-Mills Theory
Davide Gaiotto, Edward Witten
We study boundary conditions in N=4 super Yang-Mills theory that preserve one-half the supersymmetry. The obvious Dirichlet boundary conditions can be modified to allow some of the…
