Graded Unitarity in the SCFT/VOA Correspondence
Arash Arabi Ardehali, Christopher Beem, Madalena Lemos +1
Vertex algebras that arise from four-dimensional, superconformal field theories inherit a collection of novel structural properties from their four-dimensional ance…
Towards a classification of graded unitary algebras
Christopher Beem, Harshal Kulkarni
We study constraints imposed by four-dimensional unitarity (formalised as graded unitarity in recent work by the first author) on possible vertex algebras arising…
Simplifying the Type Argyres-Douglas Landscape
Christopher Beem, Mario Martone, Matteo Sacchi +2
A well-established organisational principle for Argyres--Douglas-type superconformal field theories in four dimensions is to characterise such theories by the data…
Free field realizations for rank-one SCFTs
Christopher Beem, Anirudh Deb, Mario Martone +2
In this paper, we construct the associated vertex operator algebras for all superconformal field theories of rank one. We give a uniform presentation through free-f…
