Quantum State of a Gravitating Spacetime Region

Raphael Bousso, Sami Kaya, Guanda Lin +1

We associate a gravitational Hilbert space $H_{σ}$ to any closed compact $(d - 1)$ -manifold $σ$ with real metric. A quantum state $J (σ)$ is a $d$ -manifold bounded by…

Quantum State of a Gravitating Region

Raphael Bousso, Sami Kaya, Guanda Lin +1

We propose that any compact $d$ -manifold with elliptic data, $J$ , prepares a quantum state $∣ J ⟩$ on its $(d - 1)$ -boundary $σ$ . Elliptic data consists of me…
