The exact Schur index in closed form
Yiwen Pan, Wolfger Peelaers
The Schur limit of the superconformal index of a four-dimensional N = 2 superconformal field theory encodes rich physical information about the protected spectrum of the theory. Fo…
New N=2 superconformal field theories from S-folds
Simone Giacomelli, Carlo Meneghelli, Wolfger Peelaers
We study the four-dimensional N=2 superconformal field theories that describe D3-branes probing the recently constructed N=2 S-folds in F-theory. We introduce a novel, infinite cla…
Maximally Supersymmetric RG Flows in 4D and Integrability
Joao Caetano, Wolfger Peelaers, Leonardo Rastelli
We revisit the leading irrelevant deformation of Super Yang-Mills theory that preserves sixteen supercharges. We consider the deformed theory on $S^3 \times \mathbb…
Argyres-Douglas Theories in Class S Without Irregularity
Christopher Beem, Wolfger Peelaers
We make a preliminary investigation into twisted theories of class S. Contrary to a common piece of folklore, we establish that theories of this type realise a variety of…
Deformation quantizations from vertex operator algebras
Yiwen Pan, Wolfger Peelaers
In this note we address the question whether one can recover from the vertex operator algebra associated with a four-dimensional N=2 superconformal field theory the deformation qua…
VOAs and rank-two instanton SCFTs
Christopher Beem, Carlo Meneghelli, Wolfger Peelaers +1
We analyze the N=2 superconformal field theories that arise when a pair of D3-branes probe an F-theory singularity from the perspective of the associated vertex operator algebra. W…
Schur correlation functions on
Yiwen Pan, Wolfger Peelaers
The Schur limit of the superconformal index of four-dimensional superconformal field theories has been shown to equal the supercharacter of the vacuum module of thei…
Chiral Algebras, Localization and Surface Defects
Yiwen Pan, Wolfger Peelaers
Four-dimensional N = 2 superconformal quantum field theories contain a subsector carrying the structure of a chiral algebra. Using localization techniques, we show for the free hyp…
Intersecting Surface Defects and Instanton Partition Functions
Yiwen Pan, Wolfger Peelaers
We analyze intersecting surface defects inserted in interacting four-dimensional N = 2 supersymmetric quantum field theories. We employ the realization of a class of such systems a…
Intersecting Surface Defects and Two-Dimensional CFT
Jaume Gomis, Bruno Le Floch, Yiwen Pan +1
We initiate the study of intersecting surface operators/defects in four-dimensional quantum field theories (QFTs). We characterize these defects by coupled 4d/2d/0d theories constr…
Deformation quantization and superconformal symmetry in three dimensions
Christopher Beem, Wolfger Peelaers, Leonardo Rastelli
We investigate the structure of certain protected operator algebras that arise in three-dimensional N=4 superconformal field theories. We find that these algebras can be understood…
Ellipsoid partition function from Seiberg-Witten monopoles
Yiwen Pan, Wolfger Peelaers
We study Higgs branch localization of N=2 supersymmetric theories placed on compact Euclidean manifolds. We analyze the resulting localization equations in detail on the four-spher…
Chiral Algebras for Trinion Theories
Madalena Lemos, Wolfger Peelaers
It was recently understood that one can identify a chiral algebra in any four-dimensional N=2 superconformal theory. In this note, we conjecture the full set of generators of the c…
Chiral algebras of class S
Christopher Beem, Wolfger Peelaers, Leonardo Rastelli +1
Four-dimensional N=2 superconformal field theories have families of protected correlation functions that possess the structure of two-dimensional chiral algebras. In this paper, we…
Higgs branch localization of theories on
Wolfger Peelaers
We apply the method of Higgs branch localization to the supersymmetric partition function on As a result, we show that it can be written as the pro…
Higgs branch localization in three dimensions
Francesco Benini, Wolfger Peelaers
We show that the supersymmetric partition function of three-dimensional N=2 R-symmetric Chern-Simons-matter theories on the squashed S^3 and on S^2 x S^1 can be computed with the s…
Infinite Chiral Symmetry in Four Dimensions
Christopher Beem, Madalena Lemos, Pedro Liendo +3
We describe a new correspondence between four-dimensional conformal field theories with extended supersymmetry and two-dimensional chiral algebras. The meromorphic correlators of t…
The Superconformal Index of Class S Theories of Type D
Madalena Lemos, Wolfger Peelaers, Leonardo Rastelli
We consider the superconformal index of class S theories of type D, which arise by compactification of the (2,0) D_n theories on a punctured Riemann surface C. We also allow for th…
