Quantum Gravity on the computer 2.0, Jena, Germany --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=28264 Starting: 2024-09-09 to 2024-09-13 Location: Jena, Germany Additional Information: https://indico.tpi.uni-jena.de/e/qgcomputer Contact: sebastian.steinhaus[AT]uni-jena.de Computational methods and numerical simulations play an increasingly important role in various approaches to quantum gravity. In recent years we have seen emerging evidence that Lorentzian quantum gravity approaches with quantum amplitudes have intriguing properties, e.g. destructive interference of undesirable configurations. However, these are also particularly challenging to tackle numerically. In this workshop, we want to see how and with which methods different approaches address these challenges. Moreover, we also want to explore which future questions and observables are interesting from different perspectives. The focus of this workshop is not high performance computing, but rather how to use computers in quantum gravity, explaining the methods used and whether they might be transferable to other approaches. Confirmed speakers: Georg Bergner (FSU Jena) Bianca Dittrich (Perimeter Institute) Pietro Dona' (CPT Marseille) Renata Ferrero (FAU Erlangen) Benjamin Knorr (Nordita) Daniel Nemeth (Radboud University Nijmegen) Andreas Pithis (FSU Jena) Dongxue Qu (Perimeter Institute) Hanno Sahlmann (FAU Erlangen) Yuki Sato (University of Fukui) Sumati Surya (Raman Research Institute) Stav Zalel (Imperical College London) We plan this workshop as a hybrid event, so participation will be possible remotely via Zoom. Registration is open! We plan for up to 30 participants in person. We in particular welcome participation of PhD students and postdocs, who can also apply to present a poster for this event. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.3.

Developments, Problems, and Extensions of Electrodynamics, Bad Honnef, Germany --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=28326 Starting: 2024-08-18 to 2024-08-23 Location: Bad Honnef, Germany Additional Information: https://indico.cern.ch/event/1408269/registrations/105266/ Contact: claus.laemmerzahl[AT]zarm.uni-bremen.de Without electromagnetic fields no observations could be made and no instrument would work. This holds for the classical as well as the quantum sector of physics. Electromagnetism is the most intensely studied and used system in physics, and we have it well under control in all technical applications, including quantum optics and the new quantum technologies. However, there are still aspects of the physics of the electromagnetic field to be investigated, and there are also open problems in the understanding and consistent description of all electromagnetic phenomena, like problems in the radiation reaction of charged particles and divergence in the self energy. Some of these problems could be solved by, e.g., non-linear, non-local or non-homogeneos (massive) extensions of the Maxwell equations. Furthermore, theories of quantum gravity also are expected to modifiy fundamental equations such as the Maxwell equations. Accordingly, it is very reasonable and timely to discuss general extensions of the Maxwell equations in a systematic way and to explore possible effects on laboratory up to astrophysical and cosmological scales. This is the topic of this binational WE-Heraeus-seminar. For all participants, complimentary on-site and full-board accommodation is provided by the Wilhelm and Else Heraeus Foundation, and there is no conference fee. Please note that the total number of participants is limited. Please note also that for postdoctoral researchers, PhD students, and graduate students it is mandatory to present a poster and, thus, to submit an abstract. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.9.

News ============================================== 3.1. New book: Solitons, Instantons, and Twistors (2nd edition) OUP by Maciej Dunajski ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2024/06/03/new-book-solitons-instantons-... Additional Information: https://global.oup.com/academic/product/solitons-instantons-and-twistors-9780198872542?lang=en&cc=gb Most nonlinear differential equations arising in natural sciences admit chaotic behaviour and cannot be solved analytically. Integrable systems lie on the other extreme. They possess regular, stable, and well-behaved solutions known as solitons and instantons. These solutions play important roles in pure and applied mathematics as well as in theoretical physics where they describe configurations topologically different from vacuum. While integrable equations in lower space-time dimensions can be solved using the inverse scattering transform, the higher-dimensional examples of anti-self-dual Yang-Mills and Einstein equations require twistor theory. Both techniques rely on an ability to represent nonlinear equations as compatibility conditions for overdetermined systems of linear differential equations. The book provides a self-contained and accessible introduction to the subject. It starts with an introduction to integrability of ordinary and partial differential equations. Subsequent chapters explore symmetry analysis, gauge theory, vortices, gravitational instantons, twistor transforms, and anti-self-duality equations. The three appendices cover basic differential geometry, complex manifold theory, and the exterior differential system. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3.2.

Additional Information: http://einsteintoolkit.org/about/releases/ET_2024_05_announcement.html We are pleased to announce the twenty-eighth release (code name "Lev Landau") of the Einstein Toolkit, an open-source, community-developed software infrastructure for relativistic astrophysics. The major changes in this release include: One new thorn has been added: * NewRadX -- This thorn provides radiative outer boundaries for the CarpetX driver. Updated thorns: * GRHayL-based IllinoisGRMHD -- this release introduces entropy evolution, tabulated equation of state, and piecewise polytrope support * Baikal(Vacuum) -- updated to use the new version of the Python code generator NRPy 2.0 * GRHayLHD(X) -- now has a tabulated EOS * Kuibit -- now supports reading the OpenPMD files generated by CarpetX In addition, bug fixes accumulated since the previous release in Nov 2023 have been included. Including ticket number 2647, correction to the WENO coefficients. The Einstein Toolkit is a collection of software components and tools for simulating and analyzing general relativistic astrophysical systems. It builds on numerous software efforts in the numerical relativity community, including codes to compute initial data parameters, the spacetime evolution codes Baikal, lean_public, and McLachlan, analysis codes to compute horizon characteristics and gravitational waves, the Carpet AMR infrastructure, and the relativistic (magneto)hydrodynamics codes GRHayLHD, GRHayLHDX, GRHydro, and IllinoisGRMHD. Data analysis and post-processing are handled by the kuibit library. The Einstein Toolkit also contains a 1D self-force code. For parts of the toolkit, the Cactus Framework is used as the underlying computational infrastructure, providing large-scale parallelization, general computational components, and a model for collaborative, portable code development. The Einstein Toolkit uses a distributed software model. Its different modules are developed, distributed, and supported either by the core team of Einstein Toolkit Maintainers or by individual groups. Where modules are provided by external groups, the Einstein Toolkit Maintainers ensure quality control for modules included in the toolkit and help coordinate support. The Einstein Toolkit Maintainers currently involve staff and faculty from five different institutions and host weekly meetings that are open to anyone. Guiding principles for the design and implementation of the toolkit include: open, community-driven software development; well thought-out and stable interfaces; separation of physics software from computational science infrastructure; provision of complete working production code; training and education for a new generation of researchers.
