RG flows, Non-Invertible Symmetries and Matrix Factorisations
Federico Ambrosino, Matthias R. Gaberdiel, Yu Nakayama
We study the behaviour of the topological defect lines of the minimal models that are preserved by the least relevant perturbation to first order. It is u…
Non-planar corrections in the symmetric orbifold
Matthias R. Gaberdiel, Beat Nairz, Cheng Peng
We calculate the non-planar corrections to the anomalous dimensions of certain quarter BPS states in the symmetric product orbifold . We find…
Defects in N=1 minimal models and RG flows
Matthias R. Gaberdiel, Lasse Merkens
Utilising the symmetry constraints of suitable topological defects, the possible RG flows of N=1 superconformal minimal models are studied. We first employ a coset description that…
Anomalous dimensions in the symmetric orbifold
Matthias R. Gaberdiel, Felix Lichtner, Beat Nairz
Recently, the anomalous conformal dimensions of the symmetric orbifold under the -cycle twisted sector deformation were calculated using the perturbed action of the supercharges…
A localising AdS sigma model
Lorenz Eberhardt, Matthias R. Gaberdiel
We construct a CFT with symmetry at the `tensionless' point , which is distinct from the usual WZW model. Thi…
Structure of the chiral algebra
Matthias R. Gaberdiel, Wei Li
The chiral algebra of 4D SU super-Yang-Mills theory is an superconformal vertex operator algebra. We analyse the structure of this algebra by s…
