• Abstract: We consider a global quantum system (the "Universe") satisfying a double constraint, both on total energy and total momentum. Generalizing the Page and Wootters quantum clock formalism, we provide a model of 3+1 dimensional, non-relativistic, quantum spacetime emerging from entanglement among different subsystems in a globally "timeless" and "positionless" Universe.

• Does the Universe have its own mass? [62.997667081978825]
  The mass of the universe is a distribution of non-zero values of gravitational constraints. A formulation of the Euclidean quantum theory of gravity is also proposed to determine the initial state. Being unrelated to ordinary matter, the distribution of its own mass affects the geometry of space.

• Entanglement Entropy of Non-Hermitian Eigenstates and the Ginibre Ensemble [0.0]
  Entanglement entropy is a powerful tool in characterizing universal features in quantum many-body systems. We show that for Hamiltonians displaying non-Hermitian many-body quantum chaos, the entanglement entropy of typical eigenstates is greatly suppressed.

  We show that unitarity for a clock that encounters a classical singularity at finite time implies quantum resolution, but for a clock that encounters future infinity at finite time leads to a quantum recollapse.

  We argue that the flat spacetime with inexact quantum mechanics in it is dual to the de Sitter spacetime with exact quantum mechanics in it. The vanishing smallness of the observed positive cosmological constant suggests the extraordinary exactness of the bulk quantum mechanics in the flat spacetime.

  The Hamiltonian of an evolving Universe is shown to be formally equivalent to that of a driven quantum system. It is shown that periodic cyclic cosmologies are generically prohibited due to their correspondence with periodically-driven quantum systems.

We also discuss the question of switching between different internal times as well as the Montevideo interpretation of quantum theory.
