  1. Interpretations of Quantum Theory in the Light of Modern Cosmology.Mario Castagnino, Sebastian Fortin, Roberto Laura & Daniel Sudarsky - 2017 - Foundations of Physics 47 (11):1387-1422.
    The difficult issues related to the interpretation of quantum mechanics and, in particular, the “measurement problem” are revisited using as motivation the process of generation of structure from quantum fluctuations in inflationary cosmology. The unessential mathematical complexity of the particular problem is bypassed, facilitating the discussion of the conceptual issues, by considering, within the paradigm set up by the cosmological problem, another problem where symmetry serves as a focal point: a simplified version of Mott’s problem.

  • Contrary Inferences in Consistent Histories and a Set Selection Criterion.Petros Wallden - 2014 - Foundations of Physics 44 (11):1195-1215.
    The best developed formulation of closed system quantum theory that handles multiple-time statements, is the consistent (or decoherent) histories approach. The most important weaknesses of the approach is that it gives rise to many different consistent sets, and it has been argued that a complete interpretation should be accompanied with a natural mechanism leading to a (possibly) unique preferred consistent set. The existence of multiple consistent sets becomes more problematic because it allows the existence of contrary inferences [1]. We analyse (...)

  • The Weight of Collapse: Dynamical Reduction Models in General Relativistic Contexts.Elias Okon & Daniel Sudarsky - unknown
    Inspired by possible connections between gravity and foundational question in quantum theory, we consider an approach for the adaptation of objective collapse models to a general relativistic context. We apply these ideas to a list of open problems in cosmology and quantum gravity, such as the emergence of seeds of cosmic structure, the black hole information issue, the problem of time in quantum gravity and, in a more speculative manner, to the nature of dark energy and the origin of the (...)

  • The Consistent Histories Formalism and the Measurement Problem.Elias Okon & Daniel Sudarsky - 2015 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 52 (Part B):217-222.
    In response to a recent rebuttal of Okon and Sudarsky presented in Griffiths, we defend the claim that the Consistent Histories formulation of quantum mechanics does not solve the measurement problem. In order to do so, we argue that satisfactory solutions to the problem must not only not contain anthropomorphic terms at the fundamental level, but also that applications of the formalism to concrete situations should not require any input not contained in the description of the situation at hand at (...)

  • The Meaning of the Wave Function: In Search of the Ontology of Quantum Mechanics.Shan Gao - unknown
    The meaning of the wave function has been a hot topic of debate since the early days of quantum mechanics. Recent years have witnessed a growing interest in this long-standing question. Is the wave function ontic, directly representing a state of reality, or epistemic, merely representing a state of knowledge, or something else? If the wave function is not ontic, then what, if any, is the underlying state of reality? If the wave function is indeed ontic, then exactly what physical (...)

  • Measurements According to Consistent Histories.Elias Okon & Daniel Sudarsky - 2014 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 48 (1):7-12.
    We critically evaluate the treatment of the notion of measurement in the Consistent Histories approach to quantum mechanics. We find such a treatment unsatisfactory because it relies, often implicitly, on elements external to those provided by the formalism. In particular, we note that, in order for the formalism to be informative when dealing with measurement scenarios, one needs to assume that the appropriate choice of framework is such that apparatuses are always in states of well defined pointer positions after measurements.

  • Histories in Quantum Mechanics: Distinguishing Between Formalism and Interpretation.Marcelo Losada & Olimpia Lombardi - 2018 - European Journal for Philosophy of Science 8 (3):367-394.
    In spite of being a well articulated proposal, the theory of quantum histories, in its different versions, suffers from certain difficulties that have been pointed out in the literature. Nevertheless, two facets of the proposal have not been sufficiently stressed. On the one hand, it is a non-collapse formalism that should be technically appropriate to supply descriptions based on quantum properties at different times. On the other hand, it intends to provide an interpretation of quantum mechanics that solves the traditional (...)
