arXiv:2508.20166v1 Announce Type: new Abstract: Many-body quantum systems with local interactions undergo “sudden death of entanglement” at high temperatures, whereby thermal states become classical mixtures of product states. We investigate whether symmetry constraints can prevent this phenomenon. We prove that strongly symmetric thermal states (canonical ensemble) of generic Hamiltonians with on

arXiv:2508.15871v1 Announce Type: new Abstract: The von Neumann attitude on such a deep interpretational question as the role of a human observer in order for the quantum description of measurement to be consistent has been long misrepresented. The large majority of the subsequent literature ascribed to von Neumann a radical view, according to which not only the collapse was in itself a truly phys

arXiv:2508.15863v1 Announce Type: new Abstract: There are long standing questions about the Big Bang What were its properties? Was there nothing before it? Was the universe always here? Many conceptual issues revolve around time. This paper gives a novel model based on McTaggarts temporal distinction between the A-series future-present-past and B-series earlier-times to later times. These series a

arXiv:2508.01803v2 Announce Type: replace-cross Abstract: We show that the arrow of time is intimately related to the geometry and topology of the whole universe, and is therefore best understood as a cosmological phenomenon.
