The Energy-Momentum-News Complex near Future Null Infinity
Jelle Hartong, Emil Have, Vijay Nenmeli +1
We study asymptotically flat vacuum solutions of general relativity in three and four dimensions, with an emphasis on the geometric structures that emerge near null infinity. We co…
On Carrollian Loop Amplitudes for Gauge Theory and Gravity
Vijay Nenmeli, Bin Zhu
Carrollian amplitudes are scattering amplitudes of massless particles written in position space at null infinity. We study various aspects of Carrollian amplitudes for gauge theory…
From AdS to Flat Space: Massive Spin-2 Fields
Vijay Nenmeli, Arvind Shekar, Mritunjay Verma
We analyze a bulk effective field theory in AdS containing a U(1)-charged massive spin-2 field coupled to a gauge field, by performing the required holographic renormalization, and…
Boundary Energy-Momentum Tensors for Asymptotically Flat Spacetimes
Jelle Hartong, Emil Have, Vijay Nenmeli +1
We consider 3D and 4D asymptotically flat spacetimes near future null infinity endowed with the most general allowed Carroll geometry. We define a boundary energy-momentum tensor b…
