WebJul 21, 2024 · Hartle-Hawking state in the real-time formalism. Atsushi Higuchi, William C. C. Lima. We study self-interacting massive scalar field theory in static spacetimes with a bifurcate Killing horizon and a wedge reflection. In this theory the Hartle-Hawking state is defined to have the -point correlation functions obtained by analytically continuing ... WebTo apply the Hartle-Hawking prescription, we look for a space that is bounded by S1×S2×Mand that supports a classical solution to the string equations of motion with an Euclidean signature metric. In the following, we will construct such a space and show that the topologicalstring partition function gives the Hartle-Hawkingtype
WebMar 2, 2024 · In theoretical physics, the Hartle–Hawking state, named after James Hartle and Stephen Hawking, is a proposal concerning the state of the universe prior to the Planck epoch.
