Absolute entropy and the observer's no-boundary state
Andreas Blommaert, Jonah Kudler-Flam, Erez Y. Urbach
We investigate the no-boundary proposal for closed universes with an observer. We argue that the observer's no-boundary state is the identity operator on the physical Hilbert space…
Gravitons on the edge
Andreas Blommaert, Sean Colin-Ellerin
We study free graviton entanglement between Rindler wedges in the Minkowski vacuum state via the Euclidean path integral. We follow Kabat's method for computing the conical entropy…
Eigenbranes in Jackiw-Teitelboim gravity
Andreas Blommaert, Thomas G. Mertens, Henri Verschelde
It was proven recently that JT gravity can be defined as an ensemble of L x L Hermitian matrices. We point out that the eigenvalues of the matrix correspond in JT gravity to FZZT-t…
