Damped perturbations in the no-boundary state
Juan Diaz Dorronsoro, Jonathan J. Halliwell, James B. Hartle +3
We evaluate the no-boundary path integral exactly in a Bianchi IX minisuperspace with two scale factors. In this model the no-boundary proposal can be implemented by requiring one…
Towards an explicit model of large field inflation
Juan Diaz Dorronsoro, Marjorie Schillo
The unwinding inflation mechanism is studied in a type IIB flux compactification where all moduli are stabilized using flux, non-perturbative effects, and the leading alpha' correc…
The Real No-Boundary Wave Function in Lorentzian Quantum Cosmology
Juan Diaz Dorronsoro, Jonathan J. Halliwell, James B. Hartle +2
It is shown that the standard no-boundary wave function has a natural expression in terms of a Lorentzian path integral with its contour defined by Picard-Lefschetz theory. The wav…
Domain wall seeds in CSO-gauged supergravity
Juan Diaz Dorronsoro, Harold Erbin, Thomas Van Riet
Gravitational domain wall solutions in gauged supergravity are often constructed within truncations that do not include vectors. As a consequence the gauge group is only a global s…
