  1. A general conceptual framework for decoherence in closed and open systems.Mario Castagnino, Roberto Laura & Olimpia Lombardi - 2007 - Philosophy of Science 74 (5):968-980.
    In this paper we argue that the formalisms for decoherence originally devised to deal just with closed or open systems can be subsumed under a general conceptual framework, in such a way that they cooperate in the understanding of the same physical phenomenon. This new perspective dissolves certain conceptual difficulties of the einselection program but, at the same time, shows that the openness of the quantum system is not the essential ingredient for decoherence. †To contact the authors, please write to: (...)

    Time Translation of Quantum Properties.Roberto Laura & Leonardo Vanni - 2009 - Foundations of Physics 39 (2):160-173.
    Based on the notion of time translation, we develop a formalism to deal with the logic of quantum properties at different times. In our formalism it is possible to enlarge the usual notion of context to include composed properties involving properties at different times. We compare our results with the theory of consistent histories.

    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.
