  1. Deriving General Relativity from String Theory.Nick Huggett & Tiziana Vistarini - 2015 - Philosophy of Science 82 (5):1163-1174.
    Weyl symmetry of the classical bosonic string Lagrangian is broken by quantization, with profound consequences described here. Reimposing symmetry requires that the background space-time satisfy the equations of general relativity: general relativity, hence classical space-time as we know it, arises from string theory. We investigate the logical role of Weyl symmetry in this explanation of general relativity: it is not an independent physical postulate but required in quantum string theory, so from a certain point of view it plays only a (...)

  2. (1 other version)Time in quantum gravity.Nick Huggett, Tiziana Vistarini & Christian Wuthrich - 2012 - .
    Quantum gravity--the marriage of quantum physics with general relativity--is bound to contain deep and important lessons for the nature of physical time. Some of these lessons shall be canvassed here, particularly as they arise from quantum general relativity and string theory and related approaches. Of particular interest is the question of which of the intuitive aspects of time will turn out to be fundamental, and which 'emergent' in some sense.

    The Emergence of Spacetime in String Theory.Tiziana Vistarini - 2019 - London: Routledge.
    The nature of space and time is one of the most fascinating and fundamental areas of the philosophy of physics. This study aims to provide a complete account of current debates in the application of spacetime to string theory. String theory has been an important discipline within physics for many years but is only now being applied to the problems faced by philosophers of science. This emerging area of physics is discussed in relation to a number of theories including general (...)

    Two open questions in the reformist agenda of the philosophy of cognitive science.Aurora Alegiani, Massimo Marraffa & Tiziana Vistarini - 2023 - Rivista Internazionale di Filosofia e Psicologia 14:59-73.
    _Abstract_: In this paper we carve out a _reformist_ agenda within the debate on the foundations of cognitive science, incorporating some important ideas from the 4E cognition literature into the computational-representational framework. We are deeply sympathetic to this reformist program since we think that, despite strong criticism of the concept of computation and the related notion of representation, computational models should still be at the core of the study of mind. At the same time, we recognize the need for a (...)

  5. Entanglement Exchange And Bohmian Mechanics.Nick Huggett & Tiziana Vistarini - 2010 - Manuscrito 33 (1):223-242.
    This paper explains the phenomenon of `entanglement exchange' within the Bohmian approach to quantum mechanics. After explaining Bohmian mechanics and entanglement exchange, in which pairs of particles become entangled without ever interacting causally in the usual, unitary sense, our aim is to use this example, to illustrate how the `pilot wave' mediates non-local correlations. The discussion thus gives a useful new way to think about entanglement exchange, and clarifies the structure of Bohmian mechanics.

  6. Extending Lewisian modal metaphysics in light of Quantum Gravity.Tiziana Vistarini - 2020 - In Nick Huggett, Keizo Matsubara & Christian Wüthrich (eds.), Beyond Spacetime: The Foundations of Quantum Gravity. Cambridge: Cambridge University Press..
    It has been argued within some philosophy of quantum gravity circles that endorsing Lewisian modal metaphysics is incompatible with endorsing the fundamental physical ontology of any quantum gravity theory. Speaking concisely, the unsolvable tension would be between Lewis' metaphysical commitment to the fundamentality of space and time, and the physical lesson of quantum gravity about the disappearance of space and time from the fundamental structure of the world. In this essay I argue against the idea that the tension is unsolvable. (...)
