Worldline Higher Spin Gravity
Minkyeu Cho, Euihun Joung, Taehwan Oh +1
We propose a worldline formulation of higher-spin gravity (HSG) in , based on a simple twistor action. Taken at face value, the model describes only the free propag…
Linearised gravity as edge modes & manifest duality and Lorentz covariance
Calvin Y. -R. Chen, Euihun Joung, Karapet Mkrtchyan
We present the first formulation of linearised gravity in four dimensions which is manifestly Lorentz covariant and democratic, i.e. treats the two frames related by electric-magne…
Extracting Edge Modes: Reduction of 3D and 2D Gravities
Euihun Joung, Sejin Kim
We investigate the boundary reduction of 3D Einstein gravity and JT gravity into their respective edge mode theories - namely, the Liouville and Alekseev-Shatashvili, and Schwarzia…
Higher-order chiral scalar from boundary reduction of 3d higher-spin gravity
Calvin Yi-Ren Chen, Euihun Joung, Karapet Mkrtchyan +1
We use a recently proposed covariant procedure to reduce the Chern-Simons action of three-dimensional higher-spin gravity to the boundary, resulting in a Lorentz covariant action f…
Manifestly Covariant Worldline Actions from Coadjoint Orbits. Part II: Twistorial Descriptions
Euihun Joung, TaeHwan Oh
Worldline actions for various twistor particles in AdS spacetimes are constructed from the coadjoint orbits of , and as constrained Hamiltonian…
Spinor-helicity representations of (A)dS particles of any mass
Thomas Basile, Euihun Joung, Karapet Mkrtchyan +1
The spinor-helicity representations of massive and (partially-)massless particles in four dimensional (Anti-) de Sitter spacetime are studied within the framework of the dual pair…
