Fri 30 May 13:00: Gravitational Wave Signatures of Dark Matter in Neutron Star Mergers
Binary neutron star mergers provide insights into strong-field gravity and the properties of ultra-dense nuclear matter. These events offer the potential to search for signatures of physics beyond the standard model, including dark matter. We present the first numerical-relativity simulations of binary neutron star mergers admixed with dark matter, based on constraint-solved initial data. Modeling dark matter as a non-interacting fermionic gas, we investigate the impact of varying dark matter fractions and particle masses on the merger dynamics, ejecta mass, post-merger remnant properties, and the emitted gravitational waves. Our simulations suggest that the dark matter morphology – a dense core or a diluted halo – may alter the merger outcome. Scenarios with a dark matter core tend to exhibit a higher probability of prompt collapse, while those with a dark matter halo develop a common envelope, embedding the whole binary. Furthermore, gravitational wave signals from mergers with dark matter halo configurations exhibit significant deviations from standard models when the tidal deformability is calculated in a two-fluid framework neglecting the dilute and extended nature of the halo. This highlights the need for refined models in calculating the tidal deformability when considering mergers with extended dark matter structures. These initial results provide a basis for further exploration of dark matter’s role in binary neutron star mergers and their associated gravitational wave emission and can serve as a benchmark for future observations from advanced detectors and multi-messenger astrophysics.

Thu 01 May 11:45: The past present and future of computer proof in pure mathematics research. MHMW02 - Modern History of Mathematics: Looking Ahead
According to three Fields medallists interviewed by Epoch AI in 2024 to promote a new benchmark test “AI will change math research by enhancing proof development, generating novel conjectures, lowering entry barriers, and potentially automating research in the future.” A later announcement claimed that OpenAI’s O3 system had scored well above others on the test, accompanied by the admission that OpenAI funds Epoch AI, and tht O3 had had exclusive access to the test questions for training purposes. We consider these events in the light of current technological advances, and the factors, whether technical, social or economic, leading to the ongoing adoption, or otherwise, of previous computational interventions in mathematical practice. We ask what the role of historians might be in this rapidly changing landscape.

Fri 02 May 13:00: The Black Hole Threshold
Numerical evolutions show that, in spherical symmetry, as we move through the solution space of GR to the threshold of black hole formation, the resulting spacetimes tend to display a surprising degree of simplicity. A heuristic description of this behavior, called critical collapse, has been built around this empirical fact. Less is known when symmetry is dropped. In this presentation I will review the current status of the topic, focusing in particular on the struggle to understand the situation in axisymmetry.

Thu 19 Jun 14:00: Four Generations of High-Dimensional Neural Network Potentials
Machine learning potentials (MLPs) have become an important tool for atomistic simulations in many fields, from chemistry to materials science. The reason for the popularity of MLPs is their ability to provide very accurate energies and forces, which are essentially indistinguishable from the underlying reference electronic structure calculations. Still, the computational costs are much reduced enabling large-scale simulations of complex systems. Almost two decades ago, in 2007, the introduction of high-dimensional neural network potentials (HDNNP) by Behler and Parrinello paved the way for the application of MLPs to condensed systems containing a large number of atoms. Still, the original second-generation HDNN Ps, like most current MLPs, are based on a locality approximation of the atomic interactions that are truncated at some finite distance. Third-generation MLPs contain long-range electrostatic interactions up to infinite distance and overcome this restriction to short-range energies. Still, there are surprisingly many systems in which long-range electrostatic interactions are insufficient for a physically correct description, since non-local phenomena like long-range charge transfer are essential. Such global effects can be considered in fourth-generation HDNN Ps. In this talk the evolution of HDNN Ps will be discussed along with some key systems illustrating their applicability.

Wed 30 Apr 10:15: Archives discussion session MHMW02 - Modern History of Mathematics: Looking Ahead
Modern science is a numbers game. The last century or so has seen the life sciences become ever more quantitative and data-centric. In the anglophone context, few figures have been more influential in this transformation than British statistician, geneticist and eugenicist Ronald Aylmer Fisher. In this talk I will summarise aspects of my research on Fisher’s contributions to evolutionary theory, and his advocacy of eugenics, highlighting contemporary criticisms of his work in both spheres. These critical perspectives, I suggest, underline the need for counter-histories of mathematisation, in science and in public life.

Tue 29 Apr 11:00: Axion dark matter - The Good, Bad and New ways to detect it
Axion dark matter is an interesting candidate for several reasons. Axions or axion-like particles appear in many theories beyond the standard model and there is a theoretical motivation for them to be light. They have many desirable properties, but also predict effects that are challenging for heavier, cold dark matter. I will discuss how there are observables connected to these effects that could be observed in the lab with a focus on quantum sensors, as well as novel approaches at colliders.

Thu 01 May 09:15: Freedom and control: pedagogical computing in the US and the Soviet Union MHMW02 - Modern History of Mathematics: Looking Ahead
In the mid-twentieth century, the United States and the Soviet Union came to believe that the future of each country hinged on capable technoscientific workforce. To cultivate such workforce, researchers in both countries suggested replacing human instructors with special pedagogical computers to turn learning and teaching into an effective and fully controllable process. At the same time, in the 1960s and the 1970s, both American and Soviet societies saw the rising urgency of the concept of creativity. This presentation explores how researchers in each country navigated the challenge of turning the mid-century computer, a paradigmatic command and control machine, into the technology that could cultivate creative thinking. In doing so, this talk explores the historical intersections of human sciences and computing, treating pedagogical computing as an effort in engineering human behavior and thinking.
