Gravitational redshift induces quantum interference. (arXiv:2109.00728v1 [quant-ph]) 上午10:13 | David Edward Bruschi, Andreas W. Schell | quant-ph updates on arXiv.org We use quantum field theory in curved spacetime to show that gravitational redshift induces a unitary transformation on the quantum state of propagating photons. This occurs for realistic photons characterized by a finite bandwidth, while ideal photons with sharp frequencies… Read more →

A new kind of cyclic universe. (arXiv:1904.08022v1 [gr-qc] CROSS LISTED)  hep-th updates on arXiv.org on 2019-4-20 12:59am GMT Authors: Anna Ijjas, Paul J. Steinhardt Combining intervals of ekpyrotic (ultra-slow) contraction with a (non-singular) classical bounce naturally leads to a novel cyclic theory of the universe in which the Hubble parameter, energy density and temperature oscillate periodically, but the scale factor grows by… Read more →

Searching for quantum black hole structure with the Event Horizon Telescope. (arXiv:1904.05287v1 [gr-qc] CROSS LISTED)  hep-th updates on arXiv.org on 2019-4-13 1:28am GMT Authors: Steven B. Giddings The impressive images from the Event Horizon Telescope sharpen the conflict between our observations of gravitational phenomena and the principles of quantum mechanics. Two related scenarios for reconciling quantum mechanics with the existence of… Read more →

Realism and Causality II: Retrocausality in Energetic Causal Sets

Published by on

Eliahu Cohen, Marina Cortês, Avshalom C. Elitzur, Lee Smolin (Submitted on 13 Feb 2019 (v1), last revised 19 Mar 2019 (this version, v2)) https://arxiv.org/abs/1902.05082v2 We describe a new form of retrocausality, which is found in the behaviour of a class of causal set theories, called energetic causal sets (ECS). These are discrete sets of events, connected by causal relations. They have three orders:… Read more →
