An Introduction to a Realistic Quantum Physics

Giuliano Preparata

This book is a remarkable synthesis, a clear and simple introduction to Quantum Physics with a sort of Galilean dialogue on the supreme systems of contemporary Physics. The author, whose research interests and work extended from quarks to liquid systems and from crystals to stars, introduces the common conceptual and mathematical framework of all quantum theories, realistic enough to successfully confront Nature: Quantum Field Theory applied to the study of both dilute and condensed matter. In the dilute limit, quantum mechanics is shown to be a good approximation to Quantum Field Theory. Howe

Quantum Mechanics and Reality

Virendra Singh

We begin by discussing ``What exists?'', i.e. ontology, in Classical Physics which provided a description of physical phenomena at the macroscopic level. The microworld however necessitates a introduction of Quantum ideas for its understanding. It is almost certain that the world is quantum mechanical at both microscopic as well as at macroscopic level. The problem of ontology of a Quantum world is a difficult one. It also depends on which interpretation is used. We first discuss some interpretations in which Quantum Mechanics does not provide a complete framework but has to be supplemented by extra ingredients e.g. (i) Copenhagen group of interpretations associated with the names of Niels Bohr, Heisenberg, von-Neumann, and (ii) de-Broglie-Bohm interpretations. We then look at some interpretations in which Quantum mechanics is supposed to provide the entire framework such as (i) Everett-deWitt many world, (ii) quantum histories interpretations. We conclude with some remarks on the rigidity of the formalism of quantum mechanics, which is sharp contrast to it's ontological fluidity.

The World According to Quantum Mechanics

Ulrich Mohrhoff, Manu Jaiswal

"Apart from providing a lucid introduction to the mathematical formalism and conceptual foundations of quantum mechanics, we explain why the laws of physics have the form that they do. In addition, we present a new and unique look at the quantum world, steering clear of two common errors: the error of the ψ-ontologists, who reify a calculational tool; and the error of the anti-realists, for whom physical theories are simply devices for expressing regularities among observations. The new edition of this acclaimed text adds around 200 pages on a variety of topics, such as how the founders sought to make sense of quantum mechanics, Kant's theory of science, QBism, Everettian quantum mechanics, de Broglie-Bohm theory, environmental decoherence, contextuality, nonlocality, and the paradox of subjectivity - the curious fact that the world seems to exist twice, once for us, in our minds, and once by itself, independently of us."--

Four Axiomatic Frameworks

Wonsik Choi

This paper compares four foundational frameworks: classical mechanics, relativity, quantum mechanics, and the Wonsik Reality-Renderer Architecture (WRRA). Classical mechanics specifies deterministic motion, relativity establishes dynamical spacetime and a universal causal structure, and quantum mechanics governs amplitudes, probabilities, and measurement outcomes. WRRA adds a distinct architectural layer: it asks how source information, established physical laws, renderer dynamics, hidden correlations, and observation jointly produce the experienced world.The paper formulates eight WRRA axioms covering source–renderer separation, one-time law loading, common local realization, conserved but incompletely displayed information, open event outcomes, lower-order physical phenotypes, lawful logical evolution, and fair comparison with existing theories. WRRA is presented neither as a replacement for established physics nor as a fully verified fundamental theory, but as a higher-level realization framework capable of containing classical, relativistic, and quantum laws as runtime rules while investigating how physical reality becomes observable.
