Cusped Defects: Cusp Operator Expansion, Conformal Properties and Bootstrap Applications
Lorenzo Bianchi, Andrea Cavaglià, A. David Gutiérrez +2
We analyze general properties of cusped defect lines embedded in generic conformal field theories (CFTs). We prove that suitably defined cusp scaling operators transform like prima…
A Bootstrap Study of Confinement in AdS
Lorenzo Di Pietro, Stefanos R. Kousvos, Marco Meineri +3
Yang-Mills theory in AdS with Dirichlet boundary conditions is expected to undergo a transition as the AdS radius varies, since the boundary data is incompatible with confine…
EFT meets CFT: Multiloop renormalization of higher-dimensional operators in general theories
Johan Henriksson, Stefanos R. Kousvos, Jasper Roosmale Nepveu
The renormalization of composite operators is a fundamental aspect of quantum field theory, relevant for the description of phase transitions and high energy phenomenology. We calc…
Redundancy Channels in the Conformal Bootstrap
Stefanos R. Kousvos, Andreas Stergiou
A method for obstructing symmetry enhancement in numerical conformal bootstrap calculations is proposed. Symmetry enhancement refers to situations where bootstrap studies initialis…
Exploring Replica-Potts CFTs in Two Dimensions
Stefanos R. Kousvos, Alessandro Piazza, Alessandro Vichi
We initiate a numerical conformal bootstrap study of CFTs with global symmetry. These include CFTs that can be obtained as coupled replicas of two-dimensional…
Anomalous Dimensions in Hypercubic Theories
Alexander Bednyakov, Johan Henriksson, Stefanos R. Kousvos
We perform a comprehensive perturbative study of the operator spectrum in multi-scalar theories with hypercubic global symmetry. This includes working out symmetry representations…
