  1. Chemical reduction and quantum interpretation: A case for thomistic emergence.Ryan Miller - 2023 - Foundations of Chemistry 25 (3):405-417.
    The debate between ontological reductionists and emergentists in chemistry has revolved around quantum mechanics. What Franklin and Seifert (BJPS 2020) add to the long-running dispute is an attention to the measurement problem. They contend that all three realist interpretations of the quantum formalism capable of resolving the measurement problem also obviate any need for chemical emergence. I push their argument further, arguing that the realist interpretations of quantum mechanics actually subvert the basis for reduction as well, by undercutting the idea (...)

  • Structure, shape, topology: entangled concepts in molecular chemistry.Elena Ghibaudi, Luigi Cerruti & Giovanni Villani - 2019 - Foundations of Chemistry 22 (2):279-307.
    The concepts of molecular structure and molecular shape are ubiquitous in the chemical literature, where they are often taken as synonyms, with unavoidable drawbacks in chemistry teaching. A third concept, molecular topology, is less frequent but it is a reference term in molecular research domains such as Quantitative Structure–Activity Relationships. The present paper proposes an epistemological analysis of these three notions, aimed at clarifying the nature of their relationship, as well as the contiguities and differences between them. At first, we (...)

  • On the Ontological Status of Molecular Structure: Is it Possible to Reconcile Molecular Chemistry with Quantum Mechanics?Sebastian Fortin, Martín Labarca & Olimpia Lombardi - 2022 - Foundations of Science 28 (2):709-725.
    According to classical molecular chemistry, molecules have a structure, that is, they are sets of atoms with a definite arrangements in space and held together by chemical bonds. The concept of molecular structure is central to modern chemical thought given its impressive predictive power. It is also a very useful concept in chemistry education, due to its role in the rationalization and visualization of microscopic phenomena. However, such a concept seems to find no place in the ontology described by quantum (...)

  • The case of phonons: explanatory or ontological priority.Hernán Lucas Accorinti, Sebastian Fortin, Manuel Herrera & Jesús Alberto Jaimes Arriaga - unknown
    Recent discussions about the microstructure of materials generally focus on the ontological aspects of the molecular structure. However, there are many types of substances that cannot be studied by means of the concept of molecule, for example, salts. For the quantum treatment of these substances, a new particle, called phonon, is introduced. Phonons are generally conceived as a pseudo-particle, that is, a mathematical device necessary to perform calculations but which does not have a "real" existence. In this context, the aim (...)

  • About the nature of the wave function and its dimensionality: the case of quantum chemistry.Sebastian Fortin & Jesús Alberto Jaimes Arriaga - unknown
    The problem of the 3N dimensions of the wave function is of particular interest in the philosophy of physics. In this work, we will recall the main positions about the nature and dimensionality of the wave function and we will introduce a new perspective, coming from quantum chemistry. For this, we will bring to light the formal operations that underlie the independent electron approximation. On this basis, we will point out how quantum chemistry can offer new arguments that contribute to (...)
