Abstract: In quantum information science, embezzlement refers to the counterintuitive possibility of extracting arbitrary entangled states from a reference state (the "embezzler") via local unitary operations while hardly perturbing the latter. Basic conservation laws imply that an embezzler has infinite entanglement. To study this phenomenon, we consider a pair (M, M’) of a von Neumann algebra and its commutant in standard form as the bipartite system and study how well a given pure state, i.e., a unit vector Ω in the positive cone, performs at the task of embezzling arbitrary entangled states. We find a connection to the flow of weights on M: Ω is good at embezzling if and only if the dual state ω̂ is an approximate fixed point of the flow of weights. In particular, embezzling states correspond to fixed points of the flow of weights, and the type III_1 factor can be uniquely characterized by the property that all states are embezzling. For type III_λ factors, 0<λ<=1, the value of λ can be recovered from the worst-case embezzlement performance of all bipartite pure states. The λ=0 is open. This is joint work with A. Stottmeister, H. Wilming, and R.F. Werner.

DIAS Lecture by Prof. Dr. Bernhard Siegert, Gerd Bucerius Professor for the History and Theory of Cultural Techniques at Bauhaus Universität Weimar From Filtering to Imaging - MediaNatures of Plankton (1889 – 2019) By giving the concept of “environing technologies” (Sørlin and Wormbs) a media theoretical twist, the talk undertakes to re-perspectivize the history of plankton research in the North Atlantic from the angle of a praxeology of media. The talk will be divided into four sections: First, the concept of “environing media” is explained. The remaining sections will be devoted to three historical epochs of plankton research in the North Atlantic, or more precisely to the media practices (or “Kulturtechniken”), by which we can distinguish these epochs, and which gave rise to three different “medianatures” of plankton. Thus, it can be shown that the media history of microbiological oceanography proceeds through unstable distinctions between medium and message. By conclusion one could argue that plankton as such never existed, but only the "effective range" of the media systems used in each case. About: Bernhard Siegert is Gerd Bucerius Professor for the History and Theory of Cultural Techniques at Bauhaus Universität Weimar. From 2008 to 2020 he was co-director of the International Research Center for Cultural Techniques and Media Philosophy at Weimar (IKKM). Since 2021 he leads the project “The New Real – Past, Present, and Future of Computation and the Ecologization of Cultural Techniques” funded by the NOMIS Foundation. Siegert has held visiting professorships and scholarships at UC Santa Barbara, New York University, University of British Columbia, University of Cambridge, Freie Universität Berlin, Stockholm University, and Harvard University. His many publications have drawn upon disciplines including the histories of sciences and technologies, art, literature, and data processing to deconstruct supposedly ontologically or naturally given entities in terms of a history of mediums and cultural techniques. Translations in English of his work on media theory and history have appeared as Relays: Literature as an Epoch of the Postal System (Stanford University Press, 1999) and, more recently, Cultural Techniques: Grids, Filters, Doors, and Other Articulations of the Real (Fordham University Press, 2015). The lecture takes place in the DIAS Auditorium, Fioniavej 34from 11:15 to 12:15. Everybody is welcome and no registration is needed.

Workshop Wednesday, December 13, 13:15–17:00 Tobias Nanz & Anders Engberg-Pedersen Host: DIAS in cooperation with the Department of Culture and Language (SDU), the Center for War Studies (SDU) and the Marie Skłodowska-Curie Actions Venue: DIAS seminar room Topic: The sea is an unknown smooth space. It is a space from which natural forces emanate, it is loaded with fictions that are meant to make it comprehensible. It is a space of trading and communication, but also a space of battles, war, and disruption. Since ancient times people such as coast dwellers, government officials, or military thinkers have sought to control the sea with ships and submarines and with specific media and cultural techniques. This workshop brings together perspectives from literature, media and culture studies to discuss the challenges of the sea and people’s struggle to transform the smooth space into a striated and thus controllable space. 13:15 – 13:30: Introduction 13:30 – 15:00: Panel 1 / Chair: Tobias Nanz Bernhard Siegert (BU Weimar): Trafalgar: Victory through Love and Hermeneutics Søren Frank (SDU): Coastal havoc in Peder Frederik Jensen’s Rans vilje (2023) and Holger Drachmann’s ’Efter Orkanen’ (1881) 15:00 – 15:30: Coffee and Cookies 15:30 – 17:00: Panel 2 / Chair: Anders Engberg-Pedersen Lieven Raymaekers (KU Leuven): War and the Ocean: Man, Media and Submarine Fiction Tobias Nanz (SDU): Noisy Shores.

Full programme and registration can be found here. University of Southern Denmark, The Danish Institute for Advanced Study, Odense, February 8-9, 2024. Organized by Professor Kaare Christensen and Professor Anne-Marie Mai, Danish Aging Research Center and Danish Institute for Advanced Studies, SDU. Many art critics have praised the late Beethoven, the late Goya, the late Monet, and the aging Karen Blixen, and in politics, science, and business we find examples of individuals whose old age becomes a very important period of their lives – just think of Winston Churchill and Niels Bohr. But what can the new late-style studies tell us about old age as a special phase of life and is it only for special geniuses to flourish in old age? At the workshop, we take a closer look at various examples from art, politics, and science and at the new late-style studies. In the last fifteen years, research on aging has seen a new interest in creativity in later life. International conferences and anthologies are insisting on a distinct category of productivity and creativity in aging artists. The workshop is open for all interested participants. We have organized a session of short introductions aimed at a broader and more general audience on day 1 (Thursday, February 8th, 13-16), followed by more detailed talks on day 2 (Friday, February 9th, 9.30-13.15). Speakers: Kaare Christensen, Professor, MD, PhD, DMSc, Danish Aging Research Center (DARC), Department of Public Health, Faculty of Health Sciences, University of Southern Denmark, Odense, Denmark.
