Stability in Designer Gravity
Thomas Hertog, Stefan Hollands
We study the stability of designer gravity theories, in which one considers gravity coupled to a tachyonic scalar with anti-de Sitter boundary conditions defined by a smooth functi…

A remark on alpha vacua for quantum field theories on de Sitter space
Romeo Brunetti, Klaus Fredenhagen, Stefan Hollands
It is shown that the so-called -vacua which have been proposed as candidates for states of free quantum fields on de Sitter space have infinitely strong fluctuations for typical…

Comparison between various notions of conserved charges in asymptotically AdS-spacetimes
S. Hollands, A. Ishibashi, D. Marolf
We derive hamiltionian generators of asymptotic symmetries for general relativity with asymptotic AdS boundary conditions using the ``covariant phase space'' method of Wald et al.…
