Pure connection formalism and Plebanski's second heavenly equation
Kirill Krasnov, Arthur Lipstein
Plebanski's second heavenly equation reduces the problem of finding a self-dual Einstein metric to solving a non-linear second-order PDE for a single function. Plebanski's original…
Light-cone actions and correlators of self-dual theories in AdS
Chandramouli Chowdhury, George Doran, Arthur Lipstein +3
Self-dual Yang-Mills and Einstein gravity in Euclidean AdS are useful toy models because they can be described by simple scalar Lagrangians exhibiting a new manifestation of th…
3d Carrollian Chern-Simons theory and 2d Yang-Mills
Arjun Bagchi, Arthur Lipstein, Mangesh Mandlik +1
With the goal of building a concrete co-dimension one holographically dual field theory for four dimensional asymptotically flat spacetimes (4d AFS) as a limit of AdS/CFT,…
Self-Dual Cosmology
Mariana Carrillo González, Arthur Lipstein, Silvia Nagy
We construct cosmological spacetimes with a self-dual Weyl tensor whose dynamics are described by conformally coupled scalars with only cubic self-interactions. Similar to the prev…
Soft Limits of Gluon and Graviton Correlators in Anti-de Sitter Space
Chandramouli Chowdhury, Arthur Lipstein, Jiajie Mei +1
We derive formulae for the soft limit of tree-level gluon and graviton correlators in Anti-de Sitter space, which arise from Feynman diagrams encoding the Weinberg soft theorems in…
Six-Dimensional Correlators From a Five-Dimensional Operator Product Expansion
N. Lambert, A. Lipstein, R. Mouland
In this letter we discuss the operator product expansion of scalar operators in five-dimensional field theories with an spacetime symmetry. Such theories arise…
