Holographic spacetime, black holes and quantum error correcting codes: a review
European Physical Journal C: Particles and Fields, 2022 This article reviews the progress in our understanding of the reconstruction of the bulk spacetime in the holographic correspondence from the dual field theory including an account of how these developments have led to the reproduction of the Page curve ...

Non‐contrastive transcendence as gift and challenge to science and religion
Modern Theology, Volume 41, Issue 4, Page 613-624, October 2025.Abstract This article suggests that the nature of transcendence represents a promising topic for future engagement between revision‐minded theologians in the field of science and religion and tradition‐oriented ones. It does so by drawing on Kathryn Tanner's account of non‐contrastive transcendence within the history of Christian theology to illuminate

Journal of High Energy Physics, 2019 We show that the simplest FLRW cosmological system consisting in the homo- geneous and isotropic massless Einstein-Scalar system enjoys a hidden conformal symmetry under the 1D conformal group SL(2, ℝ) acting as Mobius transformations in proper time ...

Global and microlocal aspects of Dirac operators: Propagators and Hadamard states
Mathematische Nachrichten, Volume 298, Issue 9, Page 2942-2974, September 2025.Abstract We propose a geometric approach to construct the Cauchy evolution operator for the Lorentzian Dirac operator on Cauchy‐compact globally hyperbolic 4‐manifolds. We realize the Cauchy evolution operator as the sum of two invariantly defined oscillatory integrals—the positive and negative Dirac propagators—global in space and in time, with ...

, 2006 Quantum cosmology in general denotes the application of quantum physics to the whole universe and thus gives rise to many realizations and examples, covering problems at different mathematical and conceptual levels. It is related to quantum gravity and more specifically describes the application to cosmological situations rather than the construction ...

Chaos in Quantum Cosmology [PDF]
Physical Review Letters, 1998 Much of the foundational work on quantum cosmology employs a simple minisuperspace model describing a Friedmann-Robertson-Walker universe containing a massive scalar field. We show that the classical limit of this model exhibits deterministic chaos and explore some of the consequences for the quantum theory.

New Journal of Physics, 2014 In the context of group field theory condensate cosmology, we clarify the extraction of cosmological variables from the microscopic quantum gravity degrees of freedom.

Advanced Quantum Technologies, Volume 8, Issue 9, September 2025.Hardware experiments show a single‐layer Quantum Memory Matrix booster cuts logical error sixfold and, when prepended to a [3,1,3]$[3,1,3]$ repetition code, attains 94 % logical fidelity without extra CX gates. QMM dressing also lowers variational‐training loss by 35 %, offering a measurement‐free, resource‐light route to error suppression on NISQ ...

QUANTUM COSMOLOGY WITH ROTATION
International Journal of Modern Physics A, 2005 The rotation of astronomical objects may be of a cosmological origin due to the Universe's specific angular momentum estimates proving to exceed those for spiral galaxies. The problem is expected to be solved in the framework of quantum geometrodynamics.
