Unconventional superconductors are materials that exhibit superconductivity beyond the framework of BCS or Migdal–Eliashberg theories, often characterized by novel broken symmetries in addition to the usual U(1) gauge symmetry breaking. A parallel development has recently emerged in magnetism with the discovery of altermagnets—materials with collinear but compensated magnetic order that defy classification as either conventional ferromagnets or antiferromagnets. Together, these phenomena highlight some of the most exciting frontiers in quantum materials research, offering both fundamental challenges and promising pathways toward future quantum technologies. This workshop will bring together leading experimentalists and theorists to discuss the latest developments in unconventional superconductors and magnets across a broad range of materials platforms.

Since the first experimental realization of Bose-Einstein condensation in ultracold atomic gases in 1995, there have been several substantial breakthroughs. Today, systems of bosonic or fermionic quantum gases allow for an unprecedented high level of experimental control concerning all ingredients of the underlying many-body Hamiltonian. Therefore, ultracold atomic or molecular quantum gases are considered to be ideal both for quantum simulators and quantum computations. Thus, they are best capable to simulate difficult problems in quantum many-body physics as they occur in condensed matter physics and other fields of physics and at the same time allow for developing architectures for quantum computers, which will ultimately surpass classical computers. In response to the occurrence of many new research directions in recent years, it is highly desirable to give a coherent overview over the diverse facets which are now appearing, and to reflect upon the future perspectives of the field.
