Postcarrollian gravity
Florian Ecker, Daniel Grumiller, Patricio Salgado-Rebolledo
We construct postcarrollian gravity models in two, three, and four spacetime dimensions by applying algebraic expansion methods. As a byproduct, we present the most general postcar…
Angle of Null Energy Condition Lines in Critical Spacetimes
Christian Ecker, Florian Ecker, Daniel Grumiller
We identify a new critical parameter in Choptuik's gravitational collapse: the angle at which null energy condition (NEC) saturation lines intersect at the center of the critical s…
Carroll swiftons
Florian Ecker, Daniel Grumiller, Marc Henneaux +1
We construct Carroll-invariant theories with fields propagating outside the Carroll lightcone, i.e., at a speed strictly greater than zero (`Carroll swiftons'). We first consider m…
