In-depth understanding of both hardware and system software layers turns out to be essential. A variety of conceptual as well as technical challenges need to be addressed. Emerging compute infrastructure imposes constraints on the design of discrete algorithms. Future developments are likely to imply even more fundamental adaptations of existing and emerging algorithms. Close collaboration of developers of algorithms with their colleagues from the high-performance computer industry turns out to be crucial for the formulation of meaningful requirements on both sides. We intend to focus on sparse linear algebra and graph algorithms while reaching out to a diverse set of representatives from industry combining expertise in modern accelerators, next-generation silicon, quantum and neuromorphic computing.

The International Congress on Mathematical Physics, on its three year cycle, is the most important conference of the International Association of Mathematical Physics, whose current president is Bruno Nachtergaele. It will be a major event, where new results and future challenges will be discussed, illustrating the richness and vitality of Mathematical Physics. We hope that you will all be able to attend and contribute to the success of the meeting.

The Conference on Computational Physics CCP2024 is the annual Conference in a series of meetings, that are held each year in a different city, treating all aspects of Physics that involve computer calculations, in an effort to explain the behavior of different systems in Physics. The meeting is sponsored by The International Union of Pure and Applied Physics (IUPAP), under the direction of the C20 Committee. The 2024 meeting will bring together scientists from all traditional areas in Physics, but will also extend to the new hot topics, such as Quantum Machine Learning, Neuromorphic Computing, use of AI in large-scale Physics experiments, big data and non-conventional data mining methods with a large variety of applications extending to complex systems, such as financial, and social networks, etc. The meeting is expected to provide a very fruitful environment to stimulate collaboration between scientists in different disciplines. A European Commission official from Brussels is invited to give the latest development in funding opportunities for collaborative projects.

Machine Learning methods have recently found widespread use in areas of atomistic modelling, mainly focusing on developing surrogate models for the potential energy surface with superior computational efficiency while retaining first principles accuracy. However, approaches to learning observable properties directly are just emerging and are challenged by several issues, which we intend to address in the workshop. The event is meant to support the development of a new collaborative, international network connecting different fields of research and integrating the young researchers community with the help of a scientifically diverse, interactive workshop.

The spectacular observation of gravitational waves from a binary neutron star merger by the LIGO-Virgo Collaboration (GW170817), and a successful follow-up campaign by nearly every electromagnetic telescope ushered in this new era of multi-messenger astrophysics. Much of the understanding of such events arises from numerical modeling. An important part of this modeling is the inclusion in simulations of neutrino transport, as described by Boltzmann's equation. Because of inherent computational resource limits and given the high cost of the transport equations and the complexity of neutrino-matter interactions, there is a trade-off between computational cost and physical realism in all simulations. This workshop covers various approaches to solving the neutrino transport problem in compact object mergers and core-collapse supernovae, including Monte Carlo methods, moment truncation schemes, and other techniques.

Gravitational wave science requires high-fidelity numerical simulations of the expected merger events. The Simulating eXtreme Spacetimes (SXS) collaboration has managed the development of two distinct codes for this purpose: (i) the Spectral Einstein Code (SpEC) based on pseudospectral methods, and (ii) an open-source code SpECTRE, an hp-adaptive discontinuous Galerkin scheme that also includes a sub-cell finite volume scheme in regions of strong shock formation that is ideally suited for multi-scale, multi-physics problems. SpECTRE targets problems in multi-messenger astrophysics, including neutron star mergers, core-collapse supernovae, and gamma-ray bursts. It runs at petascale and is designed for future exascale computers. Our weeklong program includes two contemporaneous activities: (i) a focused SpEC and SpECTRE code developers meeting and (ii) a SpECTRE workshop. The code developers' meeting will bring together researchers who are actively developing these codebases. The SpECTRE workshop aims to provide graduate students, postdocs, and faculty with the tools needed to install, run, and contribute to the open-source code SpECTRE. Our SpECTRE workshop will cover topics such as the generalized harmonic formulation of the Einstein field equation, general relativistic hydrodynamics, the discontinuous Galerkin method with finite volume sub-cells, the Cauchy characteristic extraction method, installing, running, and visualizing numerical simulations, and how to get involved with code development.

Institute for Advanced Study in Mathematics (IASM)

This symposium brings together mathematicians, computer scientists, chemists and physicist to address a truly multidisciplinary issue of enabling large-scale atomistically-resolved, ab initio materials modeling. Such modeling capabilities are required for understanding and rational design of materials ranging from alloys to solid electrolytes for fuel cells. There is a substantial gap in theory and computing techniques which on one hand would be able to model phenomena intrinsically requiring models with millions of atoms and on the other hand provide accuracy and insight which is today routinely achievable only for unrealistically small model systems . This is a gap between a model and a reality. To bridge it, this symposium makes brains from different research fields pull in one direction. Progress that this symposium will help accelerate will mean better computational support for the development of functional materials, with more of the development moved from time-, manpower-, and $-costly lab experimentation to in-silico design.

Emergent phenomena are the essence of condensed-matter physics and at the same time what makes the behavior of correlated materials appealing for applications. They are, however, hard to understand at a fundamental level. It is the interplay of several competing interactions — none of which can be treated as a mere perturbation, leading to the emergence of effective interactions — that makes their description a grand challenge. Addressing this problem requires mastery of a wide spectrum of theoretical concepts, ranging from materials modeling using first-principles approaches to advanced many-body methods based on dynamical mean-fields, stochastic simulations and renormalization techniques. The concepts of symmetry, topological invariance and the classification of transitions between phases are of crucial importance to bring order to the plethora of observed phenomena.

The goal of this year’s school is to provide students with an overview of the state-of-the-art in the field of emergent phases in strongly correlated systems and the many techniques used to investigate them. The program will start with fundamental models and concepts, introducing the Hubbard and Anderson Hamiltonians and their physics, and providing an overview of field-theoretical aspects of condensed-matter physics. More advanced lectures will introduce symmetries, Berry phases and topological quantum matter. The focus will then turn to emergent phenomena: superconductivity, conventional and non-conventional, Kondo and heavy-fermion behavior, Kosterlitz-Thouless transitions, Mott phases, orbital-ordering, and quantum phase transitions. The topics will be treated both from the view point of simple models and that of real materials, with an outlook on materials design from the theoretical and experimental viewpoint. The theoretical approaches covered will go from density-functional-theory-based methods to dynamical mean-field theory and quantum Monte Carlo. Experimental lectures will cover phenomena under normal and extreme conditions.
