    Olimpia Lombardi, Sebastian Fortin & Leonardo Vanni (2015). A Pluralist View About Information. Philosophy of Science 82 (5):1248-1259.
    Focusing on Shannon information, this article shows that, even on the basis of the same formalism, there may be different interpretations of the concept of information, and that disagreements may be deep enough to lead to very different conclusions about the informational characterization of certain physical situations. On this basis, a pluralist view is argued for, according to which the concept of information is primarily a formal concept that can adopt different interpretations that are not mutually exclusive, but each useful (...)

    Sebastian Fortin, Olimpia Lombardi & Juan Camilo Martínez González, Isomerism and Decoherence.
    In the present paper we address the problem of optical isomerism embodied in the socalled “Hund’s paradox”, which points to the difficulty to account for chirality by means of quantum mechanics. In particular, we explain the answer to the problem proposed by the theory of decoherence. The purpose to this article is to challenge this answer on the basis of a conceptual analysis of the phenomenon of decoherence, that reveals the limitations of the theory of decoherence to solve the difficulties (...)

    Olimpia Lombardi, Sebastian Fortin & Cristian López (2016). Deflating the Deflationary View of Information. European Journal for Philosophy of Science 6 (2):209-230.
    Christopher Timpson proposes a deflationary view about information, according to which the term ‘information’ is an abstract noun and, as a consequence, information is not part of the material contents of the world. The main purpose of the present article consists in supplying a critical analysis of this proposal, which will lead us to conclude that information is an item even more abstract than what Timpson claims. From this view, we embrace a pluralist stance that recognizes the legitimacy of different (...)

    Given the impressive success of environment-induced decoherence, nowadays no interpretation of quantum mechanics can ignore its results. The modal-Hamiltonian interpretation has proved to be effective for solving several interpretative problems but, since its actualization rule applies to closed systems, it seems to stand at odds of EID. The purpose of this paper is to show that this is not the case: the states einselected by the interaction with the environment according to EID are the eigenvectors of an actual-valued observable belonging (...)

    According to the environment-induced approach to decoherence, the split of the Universe into the degrees of freedom which are of direct interest to the observer and the remaining degrees of freedom is absolutely essential for decoherence. However, the EID approach offers no general criterion for deciding where to place the “cut” between system and environment: the environment may be “external” or “internal”. The main purpose of this paper is to argue that decoherence is a relative phenomenon, better understood from a (...)

    Olimpia Lombardi, Cristian López & Sebastian Fortin, No Information Without Manipulation.
    The aim of the present paper is to supply an elucidation of the concept of information in the communicational context. For this purpose, two traditional interpretations of the concept of information, the epistemic and the physical interpretations, will be distinguished, and their specific problems will be considered. In particular, whereas the epistemic interpretation misses an essential feature of communication, the physical interpretation faces difficulties in the quantum domain. The final goal will be to argue that the difficulties of the physical (...)

    Sebastian Fortin & Leonardo Vanni (2014). Quantum Decoherence: A Logical Perspective. Foundations of Physics 44 (12):1258-1268.
    The so-called classical limit of quantum mechanics is generally studied in terms of the decoherence of the state operator that characterizes a system. This is not the only possible approach to decoherence. In previous works we have presented the possibility of studying the classical limit in terms of the decoherence of relevant observables of the system. On the basis of this approach, in this paper we introduce the classical limit from a logical perspective, by studying the way in which the (...)

    Sebastian Fortin & Olimpia Lombardi (2014). Partial Traces in Decoherence and in Interpretation: What Do Reduced States Refer To? Foundations of Physics 44 (4):426-446.
    The interpretation of the concept of reduced state is a subtle issue that has relevant consequences when the task is the interpretation of quantum mechanics itself. The aim of this paper is to argue that reduced states are not the quantum states of subsystems in the same sense as quantum states are states of the whole composite system. After clearly stating the problem, our argument is developed in three stages. First, we consider the phenomenon of environment-induced decoherence as an example (...)
