Relativity and Quantum Theory: Under the Spell of Today’s Paradigms. (arXiv:2312.17693v1 [physics.hist-ph])   from physics.hist-ph by Stefan WeigertMon Jan 01 2024 11:29:57 (5 hours)# 1. Thomas S. Kuhn interprets the development of the (natural) sciences as a specific dynamical process. Periods of piecemeal growth of knowledge based on widely accepted paradigms are interrupted by bursts of revolutionary changes which lead to new paradigms… Read more →

Electrodynamic Aharonov-Bohm effect   from PRA – fundamentalconcepts by Pablo L. SaldanhaFri Dec 22 2023 18:00:00 (16 hours)# 1. Author(s): Pablo L. Saldanha We propose an electrodynamic Aharonov-Bohm (AB) scheme where a nonzero AB phase difference appears even if the interferometer paths do not enclose a magnetic flux and are subjected to negligible scalar potential differences during the propagation of the quantum charged… Read more →

Quantum reference frames, revisited. (arXiv:2312.03811v1 [gr-qc])   from  quant-ph  by  Matthew J. Lake, Marek Miller Fri Dec 08 2023 12:50:44 (1 day) # 1. The topic of quantum reference frames (QRFs) has attracted a great deal of attention in the recent literature. Potentially, the correct description of such frames is important for both the technological applications of quantum mechanics and… Read more →

Which black hole is spinning? Probing the origin of black-hole spin with gravitational waves. (arXiv:2311.05182v1 [astro-ph.HE])   from  gr-qc  by  Christian Adamcewicz, Paul D. Lasky, Eric Thrane Fri Nov 10 2023 11:42:01 (23 hours) # 1. Theoretical studies of angular momentum transport suggest that isolated stellar-mass black holes are born with negligible dimensionless spin magnitudes $\chi \lesssim 0.01$. However, recent… Read more →

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 →

Particle detector models from path integrals of localized quantum fields. (arXiv:2310.16083v1 [quant-ph])   from  quant-ph  by  Bruno de S. L. Torres Thu Oct 26 2023 09:32:00 (1 day) # 1. Using the Schwinger-Keldysh path integral, we draw a connection between localized quantum field theories and more commonly used models of local probes in Relativistic Quantum Information (RQI). By integrating over… Read more →
