Static vacuum metrics in (4 + 1) dimensions with Î < 0 and squashed conformal infinity
Piotr T. ChruÅciel, Jiaxin Song, Raphaela Wutte +2
We construct numerically two families of static five-dimensional Lorentzian metrics, solutions of vacuum Einstein equations with a negative cosmological constant, one with and one…
Positivity of holographic energy
Piotr T. ChruÅciel, Raphaela Wutte
We prove positivity of a weighted holographic energy for four-dimensional spacetimes with negative cosmological constant whose conformal boundary at infinity is conformally static…
Holographic is Hamiltonian, relatively
Piotr T. ChruÅciel, Raphaela Wutte
We show that a relative holographic energy coincides with the relative Hamiltonian energy.
Squeezed States in Gravity
Arunima Das, Maulik Parikh, Frank Wilczek +1
We present a general framework for the production of squeezed quantum states of the gravitational field in linearized quantum gravity. Time-dependent couplings in the quadratic par…
Aspects of Warped AdS geometries
Pierre Bieliavsky, Philippe Spindel, Raphaela Wutte
We discuss the geometry of three-dimensional warped Anti-de Sitter spaces and quotients thereof, paying special attention to their underlying group manifold nature. We perform a sy…
Hyperbolic Mass in 2+1 Dimensions
Raphaela Wutte
This short review surveys mass for two-dimensional asymptotically locally hyperbolic initial data sets. I explain the difficulties in defining mass in spatial dimension two, which…
