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…

Aspects of the negative mode problem in quantum tunneling with gravity
Sebastian F. Bramberger, Mariam Chitishvili, George Lavrelashvili
Some solutions describing vacuum decay exhibit a catastrophic instability. This, so-called negative mode problem in quantum tunneling with gravity, was discovered 34 years ago and…
