A Vision for a Bohm-Style Theory of Quantum Electrodynamics   from  quant-ph  by  Roderich Tumulka Fri Sep 13 2024 12:00:00 (1 day) # 1. arXiv:2409.07784v1 Announce Type: new Abstract: Despite many successes of quantum electrodynamics (QED), we do not presently have a good understanding of this field of physics. QED has all of the foundational problems that standard non-relativistic quantum… Read more →

On the exact solution for the Schrödinger equation

Yair Mulian For almost 75 years, the general solution for the Schrödinger equation was assumed to be generated by a time-ordered exponential known as the Dyson series. We discuss under which conditions the unitarity of this solution is broken, and additional singular dynamics emerges. Then, we provide an alternative construction that is manifestly unitary, regardless of the choice of the… Read more →

Black hole singularity resolution from unitarity   from  gr-qc  by  Steffen Gielen, Luc\’ia Men\’endez-Pidal Fri Sep 06 2024 12:00:00 (20 hours) # 1. arXiv:2409.03006v1 Announce Type: cross Abstract: We study the quantum dynamics of an interior planar AdS (anti-de Sitter) black hole, requiring unitarity in the natural time coordinate conjugate to the cosmological “constant of motion” appearing in unimodular gravity….

Magic of the Heisenberg Picture   from  quant-ph  by  Neil Dowling, Pavel Kos, Xhek Turkeshi Fri Aug 30 2024 12:00:00 (21 hours) # 1. arXiv:2408.16047v1 Announce Type: new Abstract: Magic quantifies the non-Clifford operations required for preparing a state on quantum processors and sets bounds on the classical computational complexity of simulating quantum dynamics. We study a magic resource theory… Read more →

A theory of time based on wavefunction collapse   from  gr-qc  by  Sung-Sik Lee Fri Aug 23 2024 12:15:38 (21 hours) # 1. arXiv:2408.11905v1 Announce Type: new Abstract: We propose that moments of time arise through the failed emergence of the temporal diffeomorphism as gauge symmetry, and that the passage of time is a continual process of an instantaneous state… Read more →
