    Michael Esfeld & Nicolas Gisin (2014). The GRW Flash Theory: A Relativistic Quantum Ontology of Matter in Space-Time? Philosophy of Science 81 (2):248-264.
    John Bell proposed an ontology for the GRW (Ghirardi, Rimini, and Weber) modification of quantum mechanics in terms of flashes occurring at space-time points. This article spells out the motivation for this ontology, inquires into the status of the wave function in it, critically examines the claim of its being Lorentz invariant, and considers whether it is a parsimonious but nevertheless physically adequate ontology.

    Nicolas Gisin (2012). Non-Realism: Deep Thought or a Soft Option? Foundations of Physics 42 (1):80-85.
    The claim that the observation of a violation of a Bell inequality leads to an alleged alternative between nonlocality and non-realism is annoying because of the vagueness of the second term.

    Valerio Scarani, Jean-Daniel Bancal, Antoine Suarez & Nicolas Gisin (2014). Strong Constraints on Models That Explain the Violation of Bell Inequalities with Hidden Superluminal Influences. Foundations of Physics 44 (5):523-531.
    We discuss models that attempt to provide an explanation for the violation of Bell inequalities at a distance in terms of hidden influences. These models reproduce the quantum correlations in most situations, but are restricted to produce local correlations in some configurations. The argument presented in (Bancal et al. Nat Phys 8:867, 2012) applies to all of these models, which can thus be proved to allow for faster-than-light communication. In other words, the signalling character of these models cannot remain hidden.

    N. Gisin (1983). Dissipative Quantum Dynamics for Systems Periodic in Time. Foundations of Physics 13 (7):643-654.
    A model of dissipative quantum dynamics (with a nonlinear friction term) is applied to systems periodic in time. The model is compared with the standard approaches based on the Floquet theorem. It is shown that for weak frictions the asymptotic states of the dynamics we propose are the periodic steady states which are usually postulated to be the states relevant for the statistical mechanics of time-periodic systems. A solution to the problem of nonuniqueness of the “quasienergies” is proposed. The implication (...)

    N. Gisin (1991). Propensities in a Non-Deterministic Physics. Synthese 89 (2):287 - 297.
    Propensities are presented as a generalization of classical determinism. They describe a physical reality intermediary between Laplacian determinism and pure randomness, such as in quantum mechanics. They are characterized by the fact that their values are determined by the collection of all actual properties. It is argued that they do not satisfy Kolmogorov axioms; other axioms are proposed.
