High harmonic generation (HHG) is a unique quantum light source with fundamentally new capabilities, by up-converting femtosecond lasers to very short wavelengths. This produces fully spatially and temporally coherent laser-like beams with linear or circular polarization throughout the extreme ultraviolet (EUV) and soft X-ray regions, all on a tabletop. These characteristics are ideal for capturing the coupled atomic, electronic, chemical, magnetic and structural orders, we well as transport/mechanical properties in materials. This talk will discuss applications of this new light source in nanoscience and nanotechnology, including understanding how nanoscale energy flow differs from bulk, how light can be used to tune the electronic or magnetic state of a material, and how to build perfect X-ray microscopes that can peer through buried interfaces or image spin textures in 3D.
