Systematics of Aligned Axions
Thomas C. Bachlechner, Kate Eckerle, Oliver Janssen +1
We describe a novel technique that renders theories of axions tractable, and more generally can be used to efficiently analyze a large class of periodic potentials of arbitrary…
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…
Axions of Evil
Thomas C. Bachlechner, Kate Eckerle, Oliver Janssen +1
We provide a systematic framework for theories of multiple axions. We discover a novel type of "alignment" that renders even very complex theories analytically tractable. Theories…
