Lessons for quantum cosmology from anti-de Sitter black holes
Alice Di Tucci, Michal P. Heller, Jean-Luc Lehners
Gravitational physics is arguably better understood in the presence of a negative cosmological constant than a positive one, yet there exist strong technical similarities between t…
Homogeneous Transitions during Inflation: a Description in Quantum Cosmology
Sebastian F. Bramberger, Alice Di Tucci, Jean-Luc Lehners
The usual description of inflationary fluctuations uses the framework of quantum field theory (QFT) in curved spacetime, in which quantum fluctuations are superimposed on a classic…
Quantum Incompleteness of Inflation
Alice Di Tucci, Job Feldbrugge, Jean-Luc Lehners +1
Inflation is most often described using quantum field theory (QFT) on a fixed, curved spacetime background. Such a description is valid only if the spatial volume of the region con…
The No-Boundary Proposal as a Path Integral with Robin Boundary Conditions
Alice Di Tucci, Jean-Luc Lehners
Realising the no-boundary proposal of Hartle and Hawking as a consistent gravitational path integral has been a long-standing puzzle. In particular, it was demonstrated by Feldbrug…
