Spacetime and Physical Equivalence   Fundamental limits on quantum dynamics based on entropy change. (arXiv:1707.06584v1 [quant-ph])  quant-ph updates on arXiv.org on 2017-7-21 2:13am GMT Authors: Siddhartha Das, Sumeet Khatri, George Siopsis, Mark M. Wilde It is well known in the realm of quantum mechanics and information theory that the entropy is non-decreasing for the class of unital physical processes. However, in general, the entropy… Read more →

Diffeomorphism invariance and general covariance: a pedagogical introduction   from  physics.hist-ph  by  Mateo Casariego Fri May 17 2024 14:27:26 (17 hours) # 1. arXiv:2405.09703v1 Announce Type: cross Abstract: Diffeomorphism invariance is a feature that gets sometimes highlighted as something with profound implications in the physics of spacetime. Moreover, it is often wrongly associated exclusively with General Relativity. The fact that… Read more →

The quantum gravity seeds for laws of nature   from physics.hist-ph by Vincent Lam, Daniele OritiFri Apr 19 2024 10:13:01 (1 day)# 1. arXiv:2404.12248v1 Announce Type: new Abstract: We discuss the challenges that the standard (Humean and non-Humean) accounts of laws face within the framework of quantum gravity where space and time may not be fundamental. This paper identifies core (meta)physical features that… Read more →

The paradox of infinitesimal granularity: Chaos and the reversibility of time in Newton’s theory of gravity. (arXiv:2209.03347v1 [nlin.CD])   from  gr-qc updates on arXiv.org  by  Simon Portegies Zwart, Tjarda Boekholt Sat Sep 10 2022 09:48:11 (1 hour) # 1. The fundamental laws of physics are time-symmetric, but our macroscopic experience contradicts this. The time reversibility paradox is partly a consequence… Read more →

Operational Interpretation of Quantum Fisher Information in Quantum Thermodynamics. (arXiv:2112.04694v1 [quant-ph]) 上午10:06 | Iman Marvian | quant-ph updates on arXiv.org In the framework of quantum thermodynamics preparing a quantum system in a general state requires the consumption of two distinct resources, namely, work and coherence. It has been shown that the work cost of preparing a quantum state is determined… Read more →

Aharonov-Bohm effect with an effective complex-valued vector potential. (arXiv:2101.11914v1 [quant-ph]) 上午10:14 | Ismael L. Paiva, Yakir Aharonov, Jeff Tollaksen, Mordecai Waegell | quant-ph updates on arXiv.org The interaction between a quantum charge and a quantized source of a magnetic field is considered in the Aharonov-Bohm scenario. It is shown that, if the source has a relatively small uncertainty while the… Read more →
