Quantum States Prepared by Wormholes: Long-Wavelength Deviations from Bunch-Davies
George Lavrelashvili, Jean-Luc Lehners
Wineglass wormholes mediate the nucleation of baby universes out of an asymptotically Anti-de Sitter or flat spacetime. Upon materialization, the new universe naturally undergoes a…
Birth of Inflationary Universes via Wineglass Wormholes and their No-Boundary Relatives
George Lavrelashvili, Jean-Luc Lehners
We study Euclidean wineglass wormholes, which mediate the nucleation of inflationary spacetimes from an existing spacetime with asymptotically flat or Anti-de Sitter regions. These…
Nucleating an Inflationary Universe: Euclidean Wormholes and their No-Boundary Limit
George Lavrelashvili, Jean-Luc Lehners
No-boundary instantons and Euclidean "wineglass" wormholes have both been proposed as providing suitable initial conditions for the current expanding phase of our universe, and in…
Stability of Axion-Dilaton Wormholes
Caroline Jonas, George Lavrelashvili, Jean-Luc Lehners
We study the perturbative stability of Euclidean axion-dilaton wormholes that asymptotically approach flat space, both with a massless and a massive dilaton, and focussing on homog…
A Zoo of Axionic Wormholes
Caroline Jonas, George Lavrelashvili, Jean-Luc Lehners
As was discovered some time ago by Giddings and Strominger (GS), an axion can support a wormhole geometry in the presence of a massless dilaton, as long as the dilaton coupling rem…
Scalar Lumps with Two Horizons
George Lavrelashvili, Jean-Luc Lehners
We study generalisations of the Schwarzschild-de Sitter solution in the presence of a scalar field with a potential barrier. These static, spherically symmetric solutions have two…
