Page transition for the complexity of an evaporating black hole
Violet Concepcion, Yasunori Nomura, Kyle Ritchie +1
Recent results demonstrate that there exists a sharp, Page-like transition for the complexity of subsystems of Haar-random states as their fractional subsystem size surpasses one h…

Physical Predictions in Closed Quantum Gravity
Yasunori Nomura, Tomonori Ugajin
Recent developments in gravitational path integrals indicate that the nonperturbative physical Hilbert space of a closed universe is one-dimensional within each superselection sect…

Nonperturbative Quantum Gravity in a Closed Lorentzian Universe
Yasunori Nomura, Tomonori Ugajin
We study how meaningful physical predictions can arise in nonperturbative quantum gravity in a closed Lorentzian universe. In such settings, recent developments suggest that the qu…
