Critical spacetime crystals in continuous dimensions
Christian Ecker, Florian Ecker, Daniel Grumiller +1
We numerically construct a one-parameter family of critical spacetimes in arbitrary continuous dimensions D>3. This generalizes Choptuik's D=4 solution to spherically symmetric mas…
Analytic discrete self-similar solutions of Einstein-Klein-Gordon at large D
Christian Ecker, Florian Ecker, Daniel Grumiller
Discretely self-similar solutions govern critical gravitational collapse and have been known only numerically since Choptuik's pioneering work. We construct, in closed analytic for…
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…
