A research team based at the University of Wuppertal has benefited from generous shares of Gauss Centre for Supercomputing (GCS) resources. Participating in many consortia involved in gaining a fundamental understanding of the universe’s most basic building blocks, the team combines numerical theory with experiment in pursuit of a richer understanding of how the universe and all that is in it came to be. Among its recent explorations, the team found a computational method to study under what conditions the quark-gluon plasma that dominated the early universe behaves as a ferromagnetic material—a material showing a high degree of responsiveness to magnetism. To understand under what conditions plasma can exhibit ferromagnetic behavior, the researchers try to understand how these distinct materials’ behaviors may intersect near other key spaces, such as phase transitions between solids, liquids, gases, and plasmas. Using the JUWELS supercomputer at the Jülich Supercomputing Centre (JSC), the team was able to better correlate the critical points of quark-gluon plasmas and ferromagnetic materials by shifting them mathematically where they can more readily be studied. First preliminary results were published in PoS LATTICE2021 (2022) 496, and, using the same algorithmic development the team could also conclude on the topological features of the QCD transition in Phys.Rev.D 107 (2023) 5, 054514.
