Is the H Atom Surrounded by A Cloud of Virtual Quanta Due to the Lamb Shift? IJQF Weekly Papers • quant-ph updates on arXiv.org / 22h arXiv:2607.27257v1 Announce Type: new Abstract: \abstract{The Lamb shift, one of the most fundamental interactions in atomic physics, arises from the interaction of H atoms with the electromagnetic fluctuations of the quantum vacuum. The energy shift has… Read more →

An Operational Resolution of the Third-Particle Paradox IJQF Weekly Papers • quant-ph updates on arXiv.org / 23h arXiv:2607.20815v1 Announce Type: new Abstract: We give an operational resolution of the third-particle paradox, relevant in the theory of quantum reference frames. The apparent paradox is that a system which is irrelevant in one quantum-reference-frame description can seem to become relevant after changing to another… Read more →

Exact No Signaling in Time without Temporal Classicality IJQF Weekly Papers • quant-ph updates on arXiv.org / 22h arXiv:2607.14583v1 Announce Type: new Abstract: No signaling in time (NSIT) has often been treated as the clean operational remnant of noninvasive measurability. If an earlier measurement leaves every later marginal unchanged, the temporal process appears classical. We show that this inference is false. We… Read more →
