Quantum materials, such as superconductors and topological insulators, all display exotic emergent phases with non-trivial topology that require characterisation at multiple extremes: ultrafast timescales, nanometre length scales, cryogenic temperatures, and high applied fields (magnetic, strain, pressure). This symposium covers recent progress in the multiscale advanced characterization, synthesis and theoretical modeling of exotic quantum objects and emergent phases within materials to disentangle and understand the complex interactions at these extremes. We showcase a range of characterisation techniques, including ultrafast near-field imaging and spectroscopy, attosecond spectroscopy, magnetometry, and transmission electron microscopy, and their application on multiferroics, topological insulators, Moiré van der Waals materials, and other emerging systems. The symposium will also showcase state-of-the-art material platforms such free-standing thin-film oxide membranes, stacks of two-dimensional materials, and combinations thereof. This symposium aims to highlight theoretical developments in understanding complex electronic interactions, non-equilbrium dynamics, and emergent nano-/meso-scale textures in quantum materials. The contributions will address basic scientific issues, discovery of new phenomena, limiting factors in the practical application of emergent topological phases in quantum materials and device design. This symposium aims to bring together scientific experts and young scientists from synthesis, characterization, and modeling, to foster interactions and surpass current technical limitations to the discovery of novel materials and quantum functionalities.
