Gauge / Gravity Duality course (online) --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=27504 Starting: 2024-03-11 to 2024-07-31 Location: Online Additional Information: https://indico.ictp.it/event/10600/ Contact: physicslatam[AT]gmail.com Physics Latam will offer an online advanced course in Gauge/Gravity Duality for undergraduate and graduate students in Latin America. The Gauge/Gravity Duality course, will be taught online from 11th March to 31st July 2024 by Robinson Mancilla (UC, Santa Barbara). Physics students from different universities in Latin America will be trained in AdS/CFT correspondence, Large-N methods to Field theory, Holographic dictionary, etc. Every student who successfully completes the course will receive an ICTP-PWF certificate at the end. This course provides an introduction to Gauge/Gravity duality using a bottom-up approach. Initially, it bridges the gap between standard GR/QFT courses and the advanced topics essential for understanding holography (Units 1 and 2). Unit 3 introduces the basics of the CFT side of the duality, while Unit 4 focuses on the holographic dictionary, particularly the role of symmetries. Discussions will include the GKP-Witten and extrapolate dictionaries, thermal dynamics, and the fundamentals of JT gravity. Syllabus Goals and deliverables Help students in Latin America by teaching lectures on Holography correspondence. Help students to be familiar with advanced research topics in AdS/CFT. Students will solve weekly assignments on these topics. Top students without MSc./Ph.D. will be mentored to pursue studies abroad, giving advice and recommendations about scholarships at international programs.

PAFT24 - Current Problems in Theoretical Physics: Quantum Gravity and Information, Vietri sul Mare, Italy --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=27599 Starting: 2024-03-24 to 2024-03-27 Location: Vietri Sul Mare, Italy Additional Information: https://agenda.infn.it/event/38965/ Contact: giulia.gubitosi[AT]unina.it The interplay between gravitational physics and quantum mechanics is one of the least understood areas of theoretical physics, which has attracted interest since the middle of the last century. Over the past decades there have been several interesting developments and promising new ideas have been proposed, which aim to achieve a deeper understanding of the distance/energy regimes in which both gravitational and quantum effects are expected to be relevant. The main objective of the conference "PAFT24 - Quantum Gravity and Information" is to bring together theoretical physicists and phenomenologists who are experts in complementary fields of classical gravity, high energy physics, quantum mechanics, and, in particular, quantum information. The conference will include not only seminars but also moments of debate to explore the various topics that will be addressed, to give space to a constructive exchange of ideas, but also to encourage new collaborations. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.9. Taking it to the extreme: Symmetries and dynamics of extremal black holes, Princeton, NJ, USA --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=27610 Starting: 2024-03-06 to 2024-03-08 Location: Princeton, USA Additional Information: https://pcts.princeton.edu/events/2024/taking-it-extreme-symmetries-and-dyna... Contact: benomio[AT]princeton.edu The existence of black holes is perhaps the most spectacular theoretical prediction of Einstein's theory of general relativity. Quite remarkably, black holes are fundamentally simple objects, as they are completely described by their mass, angular momentum, and charge. Maximally spinning (or charged) black holes are known as extremal black holes. Unlike sub-extremal black holes, extremal (and near-extremal) black holes have remained largely unexplored because of their numerous intricacies. In view of the most recent advances in understanding sub-extremal black holes, a more thorough study of extremal and near-extremal black holes now appears as a natural and promising direction for important future developments in the subject. The workshop aims at presenting two perspectives on extremal black holes, namely their symmetries and dynamics, via the combination of ideas from physics, mathematics, and numerical simulations. Invited speakers include: Marios Apetroaie (University of Muenster) Stefanos Aretakis (University of Toronto) Alessandra Buonanno (Albert Einstein Institute) Mihalis Dafermos (Princeton University/University of Cambridge) Will East (Perimeter Institute) Dejan Gajic (University of Leipzig) Gary Horowitz (University of California, Santa Barbara) Geoffrey Lovelace (California State University) Maria Rodriguez (Utah State University) This meeting is in person only. There will be no live stream, nor recordings. The schedule will include Flash Talks by participants. For those interested, please specify in the registration form. Organizers: Gabriele Benomio (Princeton University), Delilah Gates (Princeton University), Gustav Holzegel (University of Muenster and Imperial College London), Hengrui Zhu (Princeton University) +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ============================================== 2.

The details of the opening can be found at the accompanying link. We strongly encourage candidates with GW expertise to apply to this alternative-career opportunity that is non-tenure-track but is permanent and has many of the same benefits. In particular: * The position is fully benefitted (health care, retirement etc) and unionized with tenure-like protection. * The position becomes permanent after a 3 year probationary period. * However, unlike tenure-track positions, there is no tenure process - which means teaching, university/department service, grant-writing are all optional. * You can do your own research, mentor PhD students, and apply to grants - in fact, all of these are highly encouraged and have been done by past HPC facilitators. * Salaries for these kinds of positions are typically comparable to (or in some cases higher than) those offered for tenure track faculty positions. * You can also teach for additional pay. Teaching is not mandatory, however, unlike for tenure track positions. In addition to the above, you will be part of the U2GRC collaboration between UMassD and the University of Rhode Island (URI). We have a core group of 6 GW faculty (Sarah Caudill, Rob Coyne, Scott Field, Gaurav Khanna, Michael Puerrer, Vijay Varma) between the two institutes with wide ranging GW expertise. Three of this group were added in the past two years, and we are continuing to grow: this year, we are hoping to hire two Gravity/GW experts through positions like the above. Please submit your applications via the accompanying link by Jan 8 for full consideration, but applications will be accepted until the position is filled. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 2.2.

The Twenty-Seventh Release of the Einstein Toolkit ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=27554 Additional Information: https://einsteintoolkit.org/about/releases/ET_2023_11_announcement.html We are pleased to announce the twenty-seventh release (code name "Lise Meitner") of the Einstein Toolkit, an open-source, community-developed software infrastructure for relativistic astrophysics. The major changes in this release include: Several new arrangements and thorns have been added: * CarpetX arrangement for the new AMReX-based mesh driver and supporting thorns * GRHayLib for access to the General Relativistic Hydrodynamics Library (GRHayL) * GRHayLID for simple GR(M)HD initial data using GRHayLib (e.g. Balsara tests, isotropic gas) * GRHayLHD for GRHD evolution using GRHayL (equivalent to IllinoisGRMHD with no magnetic fields) * GRHayLIDX for CarpetX version of GRHayLID; this thorn currently runs on the host, not the gpu * GRHayLHDX for CarpetX version of GRHayLHD; this thorn currently runs on the host, not the gpu * DNSdata for importing SGRID initial data New capabilities for existing codes: * Seed_Magnetic_Fields has been updated to support both TOV and BNS magnetic fields; explicit IllinoisGRMHD scheduling dependency removed to support broader usage; some parameter options are deprecated and will be removed in the next release Deprecated functionality * Seed_Magnetic_Fields: to support the changes, parameter options were renamed; the old options are deprecated and will be removed in the next release * Seed_Magnetic_Fields_BNS is slated to be removed in the next release, as its features have been merged into Seed_Magnetic_Fields In addition, bug fixes accumulated since the previous release in May 2023 have been included. The Einstein Toolkit is a collection of software components and tools for simulating and analyzing general relativistic astrophysical systems that builds on numerous software efforts in the numerical relativity community, including code 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 is 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, and 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 provide quality control for modules for inclusion 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 for anyone to join. 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.
