Twisted scattering from Chern-Simons theory
Guillermo Arias-Tamargo, Philip Boyle Smith, Rishi Mouland +1
We consider boundary conditions of two-dimensional Dirac fermions which preserve a non-anomalous continuous symmetry which acts differently on the left- and right-movers. Such boun…
Discrete Gauging of 5d SCFTs
Guillermo Arias-Tamargo, Mario De Marco, Craig Lawrie +2
We study the gauging of discrete symmetries of the 5d rank-one SCFTs that fix the Coulomb branch coordinate but act nontrivially on the Higgs branch chiral ring. Using genera…
Non-Invertible Symmetries and Boundaries for Two-Dimensional Fermions
Guillermo Arias-Tamargo, Philip Boyle Smith, Rishi Mouland +1
We study the relation between boundary conditions and categorical symmetries of two-dimensional fermionic conformal field theories. We determine all anomaly-free invertible global…
Non-renormalisation of coupling constants from categorical symmetries in two dimensions
Guillermo Arias-Tamargo, Chris Hull, Maxwell L. Velásquez Cotini Hutt
We study the role of categorical symmetries in constraining the renormalisation of couplings in two-dimensional non-linear sigma models with Wess-Zumino term. A large class of thes…
Symmetries, anomalies, and dualities of two-dimensional Non-Linear Sigma Models
Guillermo Arias-Tamargo, Maxwell L. Velásquez Cotini Hutt
We analyse the global symmetry structure of two-dimensional Non-Linear Sigma Models with Wess-Zumino term. When the target space has a compact isometry without fixed points, the th…
Non-invertible symmetries of two-dimensional Non-Linear Sigma Models
Guillermo Arias-Tamargo, Chris Hull, Maxwell L. Velásquez Cotini Hutt
Global symmetries can be generalised to transformations generated by topological operators, including cases in which the topological operator does not have an inverse. A family of…
On brane systems with O planes -- 5d and 6d SCFTs
Mohammad Akhond, Guillermo Arias-Tamargo, Federico Carta +2
We study Higgs branches of field theories with 8 supercharges in 5 and 6 dimensions, focusing on theories realised on 5-brane webs in Type IIB with an O plane, or a D6-D8-NS5…
The Geometry of GTPs and 5d SCFTs
Guillermo Arias-Tamargo, Sebastián Franco, Diego Rodríguez-Gómez
We make progress in understanding the geometry associated to the Generalized Toric Polygons (GTPs) encoding the Physics of 5d Superconformal Field Theories (SCFTs), by exploiting t…
Disconnected gauge groups in the infrared
Guillermo Arias-Tamargo, Mario De Marco
Gauging a discrete 0-form symmetry of a QFT is a procedure that changes the global form of the gauge group but not its perturbative dynamics. In this work, we study the Seiberg-Wit…
Infrared phases of 3d massless CS-QCD and large
Guillermo Arias-Tamargo, Sergio Benvenuti, Diego Rodriguez-Gomez
We compute anomalous dimensions of quartic operators which are singlets under the global symmetry in Yang-Mills theories with Chern-Simons level in three dime…
Non-Invertible Symmetries from Discrete Gauging and Completeness of the Spectrum
Guillermo Arias-Tamargo, Diego Rodriguez-Gomez
We study global 1- and -form symmetries for gauge theories based on disconnected gauge groups which include charge conjugation. For pure gauge theories, the 1-form symmetrie…
Brain Webs for Brane Webs
Guillermo Arias-Tamargo, Yang-Hui He, Elli Heyes +2
We propose a new technique for classifying 5d Superconformal Field Theories arising from brane webs in Type IIB String Theory, using technology from Machine Learning to identify di…
The Hitchhiker's Guide to 4d Superconformal Field Theories
Mohammad Akhond, Guillermo Arias-Tamargo, Alessandro Mininno +4
Superconformal field theory with supersymmetry in four dimensional spacetime provides a prime playground to study strongly coupled phenomena in quantum field theory…
Discrete gauging and Hasse diagrams
Guillermo Arias-Tamargo, Antoine Bourget, Alessandro Pini
We analyse the Higgs branch of 4d SQCD gauge theories with non-connected gauge groups whos…
On the UV completion of the model in dimensions: a stable large-charge sector
Guillermo Arias-Tamargo, Diego Rodriguez-Gomez, Jorge G. Russo
We study large charge sectors in the model in dimensions. For , in perturbation theory, the quartic theory has a UV stable fixed point at large . It w…
Correlation functions in scalar field theory at large charge
Guillermo Arias-Tamargo, Diego Rodriguez-Gomez, Jorge G. Russo
We compute general higher-point functions in the sector of large charge operators , at large charge in theory. We find that there is a special c…
The large charge limit of scalar field theories and the Wilson-Fisher fixed point at
G. Arias-Tamargo, D. Rodriguez-Gomez, J. G. Russo
We study the sector of large charge operators ( being the complexified scalar field) in the Wilson-Fisher fixed point in dimensions that emerges when the coup…
Discrete gauge theories of charge conjugation
Guillermo Arias-Tamargo, Antoine Bourget, Alessandro Pini +1
We define gauge theories whose gauge group includes charge conjugation as well as standard transformations. When combined, these transformations form a novel type…
