Abstract

Angle-resolved photoemission spectroscopy (ARPES) is one of the most powerful tools for directly probing the electronic structure of materials, and it is rapidly evolving to meet the challenges of cutting-edge condensed matter research[1-4]. Recent developments are expanding ARPES into new dimensions, combining spin, time, and spatial resolution to explore complex quantum systems. Spin-resolved ARPES reveals spin textures and topological states that are central to valley- and spintronics and quantum materials[2]. Timeresolved ARPES captures ultrafast electron dynamics, providing insight into transient states that govern material properties[3]. Spatially resolved ARPES allows the study of nanomaterials, nanoscale inhomogeneities and engineered structures, connecting local phenomena to macroscopic behaviour[4]. 

This mini-colloquium will focus on the latest advances in integrating these capabilities into unified ARPES platforms, alongside theoretical progress in understanding spin and ultrafast photoemission processes. By bringing together experiments and theory, it will highlight how multidimensional ARPES is transforming our understanding of correlated materials, topological phases, nanostructures and quantum systems. The event aims to foster discussion and collaboration across the ARPES community, showcasing recent achievements and exploring the opportunities offered by the next generation of ARPES instrumentation.
