Quantum States Prepared by Wormholes: Long-Wavelength Deviations from Bunch-Davies
George Lavrelashvili, Jean-Luc Lehners
The paper investigates how wormhole-mediated nucleation of baby universes sets the quantum state of scalar and tensor fluctuations, showing that while short‑wavelength modes match…

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…
