Do the CMB Temperature Fluctuations Conserve Parity?   from  PRL  by  Oliver H. E. Philcox Fri Nov 03 2023 18:00:00 (14 hours) # 1. Author(s): Oliver H. E. Philcox Observations of the cosmic microwave background (CMB) have cemented the notion that the large-scale Universe is both statistically homogeneous and isotropic. But is it invariant also under reflections? To probe this we require… Read more →

Analysis on the Derivation of the Schr\”odinger Equation with Analogy to Electromagnetic Wave Equation. (arXiv:2310.12175v1 [quant-ph])   from  quant-ph  by  Xuefeng Bao Fri Oct 20 2023 09:59:30 (23 hours) # 1. The Schr\”odinger equation is universally accepted due to its excellent predictions aligning with observed results within its defined conditions. Nevertheless, it does not seem to possess the simplicity of… Read more →

Noise-Induced Quantum Synchronization   from  PRL: General Physics: Statistical and Quantum Mechanics, Quantum Information, etc.  by  Finn Schmolke and Eric Lutz Fri Dec 16 2022 18:00:00 (1 day) # 1. Author(s): Finn Schmolke and Eric Lutz Noise-induced synchronization can occur in the quantum regime as well as the classical, and by applying noise to a single spin in an arbitrarily… Read more →

Lapsing Quickly into Fatalism: Bell on Backward Causation

Travis Norsen, Huw Price This is a dialogue between Huw Price and Travis Norsen, loosely inspired by a letter that Price received from J. S. Bell in 1988. The main topic of discussion is Bell’s views about retrocausal approaches to quantum theory, and their relevance to contemporary issues. Full text

Approaches to causality and multi-agent paradoxes in non-classical theories. (arXiv:2102.02393v1 [quant-ph]) 上午10:10 | V. Vilasini | quant-ph updates on arXiv.org This thesis reports progress in the analysis of causality and multi-agent logical paradoxes in quantum and post-quantum theories. These research areas are highly relevant for the foundations of physics as well as the development of quantum technologies. In the first… Read more →

Nonlocality via Entanglement-Swapping — a Bridge Too Far?. (arXiv:2101.05370v1 [quant-ph]) 上午11:33 | Huw Price, Ken Wharton | quant-ph updates on arXiv.org A 2015 experiment by Hanson and his Delft colleagues provided new confirmation that the quantum world violates the Bell inequalities, closing some loopholes left open by previous experiments. The experiment was also taken to provide new evidence of quantum… Read more →

Quantum Nature of Black Holes: Fast Scrambling versus Echoes. (arXiv:1906.02653v1 [hep-th])  hep-th updates on arXiv.org on 2019-6-07 1:17pm GMT Authors: Krishan Saraswat, Niayesh Afshordi Two seemingly distinct notions regarding black holes have captured the imagination of theoretical physicists over the past decade: First, black holes are conjectured to be fast scramblers of information, a notion that is further supported through connections to… Read more →

Beyond the Dynamical Universe: Unifying Block Universe Physics and Time as Experienced

Theoretical physics and foundations of physics have not made much progress in the last few decades. Whether we are talking about unifying general relativity and quantum field theory (quantum gravity), explaining so-called dark energy and dark matter (cosmology), or the interpretation and implications of quantum mechanics and relativity, there is no consensus in sight. In addition, both enterprises are deeply… Read more →

Fixing extensions to General Relativity in the non-linear regime. (arXiv:1706.07421v1 [gr-qc])  hep-th updates on arXiv.org on 2017-6-24 7:39am GMT Authors: Juan Cayuso, Néstor Ortiz, Luis Lehner The question of what gravitational theory could supersede General Relativity has been central in theoretical physics for decades. Many disparate alternatives have been proposed motivated by cosmology, quantum gravity and phenomenological angles, and have been subjected to… Read more →
