Static vacuum metrics in (4 + 1) dimensions with Λ < 0 and squashed conformal infinity
Piotr T. Chruściel, 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. Chruściel, 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. Chruściel, 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…
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…
Photon rings in a holographic toy model
Stéphane Detournay, Sahaja Kanuri, Alexandru Lupsasca +3
Light circling around an astrophysical black hole can spend a long time skirting its unstably bound photon orbits before escaping to infinity. To a distant observer, this orbiting…
Cauchy problems for Einstein equations in three-dimensional spacetimes
Piotr T. Chruściel, Wan Cong, Théophile Quéau +1
We analyze existence and properties of solutions of two-dimensional general relativistic initial data sets with a negative cosmological constant, both on spacelike and characterist…
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…
Gluing-at-infinity of two-dimensional asymptotically locally hyperbolic manifolds
Piotr T. Chruściel, Raphaela Wutte
We review notions of mass of asymptotically locally Anti-de Sitter three-dimensional spacetimes, and apply them to some known solutions. For two-dimensional general relativistic in…
Boundary Conditions for Extremal Black Holes from 2d Gravity
Stéphane Detournay, Thomas Smoes, Raphaela Wutte
We devise new boundary conditions for the near-horizon geometries of extremal BTZ and Kerr black holes, as well as for the ultra-cold limit of the Kerr-de Sitter black hole. These…
Hyperbolic energy and Maskit gluings
Piotr T. Chruściel, Erwann Delay, Raphaela Wutte
We derive a formula for the energy of asymptotically locally hyperbolic (ALH) manifolds obtained by a gluing at infinity of two ALH manifolds. As an application we show that there…
Warped Flatland
Stéphane Detournay, Wout Merbis, Gim Seng Ng +1
We study warped flat geometries in three-dimensional topologically massive gravity. They are quotients of global warped flat spacetime, whose isometries are given by the 2-dimensio…
Interpolating Between Asymptotic and Near Horizon Symmetries
D. Grumiller, M. M. Sheikh-Jabbari, C. Troessaert +1
We develop basic tools and matching conditions to interpolate between asymptotic and near horizon symmetries. We focus on black holes in three dimensions. In particular, we match B…
New entropy formula for Kerr black holes
Hernan Gonzalez, Daniel Grumiller, Wout Merbis +1
We introduce a new entropy formula for Kerr black holes inspired by recent results for 3-dimensional black holes and cosmologies with soft Heisenberg hair. We show that also Kerr-T…
Higher-Spin Flat Space Cosmologies with Soft Hair
Martin Ammon, Daniel Grumiller, Stefan Prohazka +2
We present and discuss near horizon boundary conditions for flat space higher-spin gravity in three dimensions. As in related work our boundary conditions ensure regularity of the…
