Finite Charges from the Bulk Action
Robert McNees, Céline Zwikel
Constructing charges in the covariant phase space formalism often leads to formally divergent expressions, even when the fields satisfy physically acceptable fall-off conditions. T…
dS as excitation of AdS
Florian Ecker, Daniel Grumiller, Robert McNees
We introduce a family of 2D dilaton gravity models with state-dependent constant curvature so that dS emerges as an excitation of AdS. Curiously, the strong coupling region…
Universal flow equations and chaos bound saturation in 2d dilaton gravity
Daniel Grumiller, Robert McNees
We show that several features of the Jackiw-Teitelboim model are in fact universal properties of two-dimensional Maxwell-dilaton gravity theories with a broad class of asymptotics.…
Menagerie of AdS boundary conditions
Daniel Grumiller, Robert McNees, Jakob Salzer +2
We consider different sets of AdS boundary conditions for the Jackiw-Teitelboim model in the linear dilaton sector where the dilaton is allowed to fluctuate to leading order at…
Cosmological constant as confining U(1) charge in two-dimensional dilaton gravity
Daniel Grumiller, Robert McNees, Jakob Salzer
The cosmological constant is treated as a thermodynamical parameter in the framework of two-dimensional dilaton gravity. We find that the cosmological constant behaves as a U(1) ch…
Conformal gravity holography in four dimensions
D. Grumiller, M. Irakleidou, I. Lovrekovic +1
We formulate four-dimensional conformal gravity with (Anti-)de Sitter boundary conditions that are weaker than Starobinsky boundary conditions, allowing for an asymptotically suble…
