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 →

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 →
