Talk by Kleber at TUM (Mon. 14 Dec.)
by Dardashti, Radin Dec. 10, 2015

Dec. 10, 2015

Speaker: Manfred Kleber (TUM München) Date: Mon., Dec. 14 Location: Lecture hall II, Physics Department, Garching (https://www.ph.tum.de/about/visit/roomfinder/?room=5101.EG.502) Time: 17.15 Title: The story of Heisenberg's quantum mechanics Abstract: Ninety years ago the birth of quantum mechanics took place when Werner Heisenberg submitted his paper on Quantum-theoretical reinterpretation of kinematic and mechanical relations (Über quantentheoretische Umdeutung kinematischer und mechanischer Beziehungen) to Zeitschrift für Physik. [Z. Phys., 33, 879-893 (1925)]. We will show how important the historical context was for an understanding of his work and we will follow Heisenberg on the narrow path that took him from the unsuccessful old quantum mechanics to the light of the new quantum mechanics. We then discuss Heisenbergs research in the years following his scientic breakthrough.

CfP: Working Group Meeting "Philosophy of Physics" of the German Physical Society
by Dardashti, Radin Dec. 7, 2015

Dec. 7, 2015

Dear all, The Working Group “Philosophy of Physics” (AGPhil) of the German Physical Society (DPG) invites submissions for its annual workshop within the annual meeting of the DPG. Contributions on any topic in the philosophy of physics are welcome. The conference will take place at the University of Hamburg from February 29 to March 3, 2016, and will be part of the Annual Meeting of the DPG (http://hamburg16.dpg-tagungen.de/index.html?set_language=en&cl=en) The AGPhil hosts a joint symposium on “Quantum Theory and Gravitation“ with the DPG sections for gravitation and general relativity, particle physics, and mathematical foundations of physics; all of these will also organise additional workshops and talks at the University of Hamburg during the annual meeting. The keynote speakers of the AGPhil conference will be Adam Caulton (Munich), Michela Massimi (Edinburgh), J. Brian Pitts (Cambridge) and Chris Wüthrich (Geneva). If you would like to present a paper, please submit an abstract of about 200 words by 3 January, 2016, using the online-form at https://www.dpg-tagung.de/hh16/submission.html?language=en We look forward to seeing you in Hamburg! Meinard Kuhlmann, Dennis Lehmkuhl, Wolfgang Pietsch

Talk by Nick Tosh at MCMP (Wed. Dec.2)
by Dardashti, Radin Nov. 30, 2015

Nov. 30, 2015

Speaker: Nick Tosh (NUI Galway) Date: Wed., Dec. 2 Location: Ludwigstr. 31, ground floor, room 021 Time: 18:15 -⁠⁠⁠⁠⁠⁠ 19:45 Title: Ensemble realism: A new approach to statistical mechanical probability Abstract: “What we know about a body can generally be described most accurately and most simply by saying that it is one taken at random from a great number (ensemble) of bodies which are completely described.” So wrote Willard Gibbs in 1902, but with his fingers crossed, for he regarded ensembles as convenient fictions. A century later, they are still convenient, and we still have no settled account of the literal meaning of statistical mechanical probability assignments. My aim is to show how talk of ensembles might be taken seriously.

Talks by Evans and Fraser at MCMP (25. and 26. Nov)
by Dardashti, Radin Nov. 22, 2015

Nov. 22, 2015

Speaker: Peter Evans (University of Queensland) Date: Wed., Nov 25 Location: Ludwigstraße 31, ground floor, Room E21 Time: 16:15 -⁠⁠⁠⁠⁠ 17:45 Title: Quantum causal models, faithfulness and retrocausality Abstract: Wood and Spekkens (2015) argue that any causal model explaining the EPRB correlations and satisfying no-signalling must also violate the assumption that the model faithfully reproduces the statistical dependences and independences---a so-called “fine-tuning” of the causal parameters; this includes, in particular, retrocausal explanations of the EPRB correlations. I consider this analysis with a view to enumerating the possible responses an advocate of retrocausal explanations might propose. I focus on the response of Näger (2015), who argues that the central ideas of causal explanations can be saved if one accepts the possibility of a stable fine-tuning of the causal parameters. I argue that, in light of this view, a violation of faithfulness does not necessarily rule out retrocausal explanations of the EPRB correlations. ---------------------------------------------------------------- Speaker: James Fraser (University of Leeds) Date: Thu., Nov 26 Location: Ludwigstraße 31, ground floor, Room E21 Time: 12:15 -⁠⁠⁠⁠⁠ 13:45 Title: Relativity in Quantum Field Theory Abstract: There has recently been heated debate amongst philosophers of physics about which formulation of quantum field theory (QFT) ought to be the basis of philosophical investigations of high energy physics. Doreen Fraser has defended the primacy of axiomatic formulations of QFT, while David Wallace advocates the philosophical significance of cutoff QFTs. In this paper I focus on one issue underlying this dispute, namely the status of relativity in QFT. While Fraser takes QFT to incorporate a commitment to Minkowski space-time, Wallace views QFT as an effective field theory which says nothing about the fundamental nature of space-time, and is unfazed by the fact that imposing a cutoff breaks Poincaré covariance. One way out of this apparent stalemate, I suggest, is to relax the idea that there is a one preferred 'foundational' version of QFT. We can then allow that different formalisms, which incorporate different claims about space-time structure, are the appropriate objects of study for different philosophical projects. In particular, I argue that the question of whether quantum theory can be combined with fundamental Minkowski space-time structure and what we ought to believe about the world given the successes of the standard model are distinct and that it may be that axiomatic and cutoff formulations of QFT are the right starting points for each.

Talk by Padovani at MCMP (Thu. Nov. 19)
by Dardashti, Radin Nov. 16, 2015

Nov. 16, 2015

Speaker: Flavia Padovani (Drexel University) Date: Thu., Nov 19 Location: Ludwigstraße 31, ground floor, Room E21 Time: 18:15 -⁠⁠⁠⁠⁠ 19:45 Title: Measurements, Coordination, and the Problem of Representation of Physical Quantities Abstract: In his Scientific Representation, van Fraassen argues that measuring is a form of representation. In fact, every measurement pinpoints its target in accordance with specific operational rules within an already-constructed theoretical space, in which conceptual interconnections can be represented. Reichenbach’s 1920 account of coordination is particularly interesting in this connection. In his early work, however, the idea of coordination was employed not only to indicate theory-specific fundamental principles such as the ones suggested by Friedman’s relativized a priori, but also to refer to more basic principles. These are preconditions both of the individuation of physical magnitudes and of their measurement, thus necessary to approach the world through measurement in the first instance. This paper aims to reassess Reichenbach’s approach to coordination and to the representation of physical quantities in light of recent literature on measurement and scientific representation.

Talk by Maldacena at ASC (Wed. 18 Nov)
by Dardashti, Radin Nov. 13, 2015

Nov. 13, 2015

Speaker: Juan Maldacena (IAS Princeton) Date: Wed., Nov 18 Location: Theresienstr. 37/III, Room A348/349 Time: 16:15 -⁠⁠⁠⁠⁠ 18:45 Title: Quantum Mechanics and Geometry of Spacetime Abstract: Quantum mechanics is important for determining the geometry of spacetime. We will review the role of quantum fluctuations that determine the large scale structure of the universe. In some model universes we can give an alternative description of the physics in terms of a theory of particles that lives on its boundary. This implies that the geometry is an emergent property. Furthermore, entanglement plays a crucial role in the emergence of geometry. Large amounts of entanglement are conjectured to give rise to geometric connections, or wormholes, between distant and non-interacting systems.
