Unified Lagrangians for gravity and gauge theory
Yasha Neiman
We present a new Lagrangian formulation of General Relativity with cosmological constant, coupled to Yang-Mills gauge theory. The formulation has a manifest color/kinematics-dual s…
Higher-spin self-dual General Relativity: 6d and 4d pictures, covariant vs. lightcone
Yasha Neiman
We study the higher-spin extension of self-dual General Relativity (GR) with cosmological constant, proposed by Krasnov, Skvortsov and Tran. We show that this theory is actually a…
Topology Change from Pointlike Sources
Yasha Neiman, David O'Connell
In this paper we study topology-changing spacetimes occurring from pointlike sources. Following an old idea of Penrose, we will opt for a non-Hausdorff model of topology change in…
N=2 supersymmetry in the twistor description of higher-spin holography
Julian Lang, Yasha Neiman
We study the holographic duality between higher-spin (HS) gravity in 4d and free vector models in 3d, with special attention to the role of N=2 supersymmetry (SUSY). For the type-A…
