Quantum and Gradient Corrections to False Vacuum Decay on a de Sitter Background
Juan S. Cruz, Stephan Brandt, Maximilian Urban
We study the effects of a fixed de Sitter geometry background in scenarios of false vacuum decay. It is currently understood that bubble nucleation processes associated with first…
Quantum probing of null-singularities
Ivo Sachs, Marc Schneider, Maximilian Urban
We adapt the dual-null foliation to the functional Schrödinger representation of quantum field theory and study the behavior of quantum probes in plane-wave space-times near the nu…
A Quantum Complete Prelude to Inflation
Stefan Hofmann, Marc Schneider, Maximilian Urban
It is shown that the inflationary paradigm admits quantum complete extensions of space-time. The extended inflationary spacetimes still have geodesic borders, but quantum fields ar…
Unitarity in the Schroedinger Formalism of QFT in Curved Space-Time
Patrick Hager, Maximilian Urban
We review the general quantization of scalar fields in curved space-times in the Schroedinger formalism and discuss the determination of the ground-state. By explicitly computing t…
