Generating Hodges' Graviton MHV Formula with an $L w_{1 + \infty}$ Ward Identity

Alfredo Guevara, Elizabeth Himwich, Noah Miller

Hodges' formula expresses the tree-level all-multiplicity Einstein gravity MHV amplitude as a matrix determinant. In this work, we prove that Hodges' determinant is generated by an…

Spacetime $L w_{1 + \infty}$ Symmetry and Self-Dual Gravity in Plebanski Gauge

Noah Miller

The space of self-dual Einstein spacetimes in 4 dimensions is acted on by an infinite dimensional Lie algebra called the $L w_{1 + \infty}$ algebra. In this work we explain how one ca…

Path integral games with de Sitter α-vacua

Noah Miller

The $α$ -vacua are a 1-parameter family of quantum field vacua in de Sitter space which are invariant under the isometry group $S O (1, d)$ . In this work give a path integral construct…
