Although it has been\u0000suggested that a series of progressively sophisticated tests using artificial\u0000intelligence could yield increasingly significant experimental data to\u0000constrain potential resolutions to the measurement problem, no feasible\u0000experimental designs have yet been proposed. In this work, we utilize advanced\u0000deep learning technology to develop a novel experimental framework that\u0000integrates neural network-based artificial intelligence into a Bell test. This\u0000framework challenges the implicit assumptions underlying Bell tests. We\u0000demonstrate our framework through a simulation and introduce three new\u0000metric-morphing polygons, averaged Shannon entropy, and probability density\u0000map-to analyze the results. This approach enables us to determine whether\u0000quantum probability aligns with any one of these three interpretations or a\u0000hybrid of them.","PeriodicalId":501190,"journal":{"name":"arXiv - PHYS - General Physics","volume":"106 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142203363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Can the effect of an external gravitational field be incorporated in the classical kinetic theory of gases?","authors":"Satori Tsuzuki","doi":"arxiv-2409.00454","DOIUrl":"https://doi.org/arxiv-2409.00454","url":null,"abstract":"This study proposed an extension of the classical kinetic theory of gases\u0000(CKTG) that incorporates the gravitational effect on the motions of molecular\u0000particles. First, we rederived the CKTG in terms of the kinetics of constituent\u0000particles to account for the effect of accelerating particles by external\u0000gravitational fields. Consequently, we obtained an extended expression for the\u0000virial pressure in molecular dynamics under external potential fields. As\u0000indicated by our theoretical model, a pressure difference in the gravitational\u0000direction was observed in our particle collision simulations. Further analysis\u0000proved that if the external potential energy of each particle was sufficiently\u0000small (but not negligible compared to its kinetic energy), a pressure\u0000difference emerged between the walls while still maintaining the properties of\u0000equilibrium statistical mechanics, following the Maxwell--Boltzmann\u0000distribution. Notably, our model was formulated based on only fundamental\u0000knowledge of physics and is therefore suitable for educational purposes. Thus,\u0000this study obtained fundamental insights into the kinetic theory of gases under\u0000gravitational fields that are expected to be useful for both education and\u0000practical applications.","PeriodicalId":501190,"journal":{"name":"arXiv - PHYS - General Physics","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142203366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The previously constructed spacetime covariant and Lorentz\u0000invariant expressions for conserved Noether currents, superpotentials and\u0000charges are used. The Noether charges describe total energy, momentum or\u0000angular momentum of gravitating system depending on a choice of the\u0000displacement vector $xi$. To define covariant and invariant conserved\u0000quantities both in TEGR and in STEGR on needs to use external fields which are\u0000flat teleparallel connections. To determine the non-dynamical connections in\u0000TEGR and STEGR we use the unified ``turning off'' gravity principle. Besides,\u0000to analyse the Noether conserved quantities in these theories, we use the\u0000concept of ``gauges''. The gauge changing can affect the Noether conserved\u0000quantities. We highlight two ways to turn off gravity - by $M to 0$ and by $M\u0000to 0 , ~ a to 0$ which gives us different gauges in TEGR and STEGR. In both\u0000kind of gauges we get the expected values of black hole mass and angular\u0000momentum.

Symmetry breaking is fundamental\u0000in various physical contexts, such as high-energy physics, condensed matter\u0000physics, and cosmology. The study addresses how these mathematical tools enable\u0000the decomposition of complex field behaviors near singularities, revealing the\u0000intricate dynamics of symmetry breaking. Laurent series facilitate the\u0000expansion of fields into manageable terms, particularly around critical points.\u0000Residues provide a direct link between local field behavior and global physical\u0000properties, playing a crucial role in effective action formulations and\u0000renormalization processes. Winding numbers offer a topological perspective,\u0000quantifying how fields wrap around singularities and identifying stable\u0000topological structures like vortices, solitons, and monopoles. Extending these\u0000methods to (3+1) dimensions highlights the complexity of symmetry breaking in\u0000higher-dimensional scenarios, where advanced group theory and topological\u0000invariants are necessary to describe non-linear interactions. The findings\u0000underscore the importance of integrating these mathematical techniques into\u0000modern theoretical physics, with potential applications in quantum gravity,\u0000string theory, and the study of topological phases of matter.

{"title":"Causality in the maximally extended Reissner--Nordström spacetime with identifications","authors":"Andrzej Krasiński","doi":"arxiv-2409.03786","DOIUrl":"https://doi.org/arxiv-2409.03786","url":null,"abstract":"The maximally extended Reissner--Nordstr\"{o}m (RN) spacetime with $e^2 <\u0000m^2$ can be interpreted either as an infinite chain of asymptotically flat\u0000regions connected by tunnels between timelike singularities or as a set of just\u0000one asymptotically flat region and one tunnel; the repetitions of this set in\u0000the infinite chain being identified. The second interpretation gives rise to\u0000the suspicion of acausality, i.e. the possibility of sending messages to one's\u0000own past. A numerical investigation of this problem was carried out in this\u0000paper and gave the following result. Let E be the initial point of a radial\u0000timelike future-directed ingoing geodesic G, lying halfway between the outer\u0000horizon and the image of the null infinity in the maximally extended RN\u0000spacetime. Let E$'$ be the first future copy of E. It was verified whether the\u0000turning point of G will lie to the future or to the past from the past light\u0000cone (PLC) of E$'$. In the second case the breach of causality does occur. It\u0000turned out that the acausality is present when $V_E$, the timelike coordinate\u0000of E, is negative with a sufficiently large $|V_E|$, and is absent with a\u0000sufficiently large $V_E > 0$. In between these values there exists a\u0000$widetilde{V}_E$, dependent on the initial data for the geodesic, for which\u0000the turning point lies on the PLC. So, the identification does lead to\u0000acausality. Nonradial timelike and null geodesics were also investigated, and a\u0000few hitherto unknown properties of the maximal extension were revealed. For\u0000example, the singularity arc at $r = 0$ may be convex or concave, depending on\u0000the values of $m$ and $e$.","PeriodicalId":501190,"journal":{"name":"arXiv - PHYS - General Physics","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142203373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
