Observers seeing gravitational Hilbert spaces: abstract sources for an abstract path integral
Hong Zhe Chen
The gravitational path integral suggests a striking result: the Hilbert space of closed universes in each superselection sector, a so-called -sector, is one-dimensional. We deve…

Thermodynamic stability from Lorentzian path integrals and codimension-two singularities
Hong Zhe Chen
It has previously been shown how the gravitational thermal partition function can be obtained from a Lorentzian path integral. Unlike the Euclidean case, the integration contour ov…
