Null matter and the ultrarelativistic origin of hydrodynamics at zero temperature
Jay Armas, Emil Have, Gianbattista-Piero Nicosia
We uncover a universal sector of relativistic fluid dynamics by taking a novel ultrarelativistic limit in which the temperature tends to zero while the flow simultaneously approach…
Quantum carrollian bosonic strings
José Figueroa-O'Farrill, Emil Have, Niels A. Obers
We study a recently discovered carrollian bosonic string, described classically by a sigma model where both the worldsheet and the target spacetime are carrollian. After fixing the…
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…
