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…
Perturbative and Nonperturbative Studies of CFTs with MN Global Symmetry
Johan Henriksson, Andreas Stergiou
Fixed points in three dimensions described by conformal field theories with global symmetry have extensive applications in critical phenomena. Associa…
Analytic Bootstrap for Perturbative Conformal Field Theories
Johan Henriksson
Conformal field theories play a central role in theoretical physics with many applications ranging from condensed matter to string theory. The conformal bootstrap studies conformal…
Analytic and Numerical Bootstrap of CFTs with Global Symmetry in 3D
Johan Henriksson, Stefanos R. Kousvos, Andreas Stergiou
Motivated by applications to critical phenomena and open theoretical questions, we study conformal field theories with global symmetry in spacetime dimensio…
An alternative to diagrams for the critical O(N) model: dimensions and structure constants to order
Luis F. Alday, Johan Henriksson, Mark van Loon
We apply the methods of modern analytic bootstrap to the critical model in a expansion. At infinite the model possesses higher spin symmetry which is weakly broken…
