Twisted Argyres--Douglas theories: vertex algebras, Higgs branches, and double covers
Christopher Beem, Harshal Kulkarni
We investigate the associated vertex operator algebras and Higgs branches of two closely related families of generalised Argyres--Douglas theories, arising from the twisted $A_{2N}…
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…
On the semi-infinite cohomology of graded-unitary vertex algebras
Christopher Beem, Niklas Garner
Recently, the first author with A. Ardehali, M. Lemos, and L. Rastelli introduced the notion of graded unitarity for vertex algebras. This generalization of unitarity is motivated…
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…
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…
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…
