Joseph F. Keithley Award For Advances in Measurement Science Talk: Science Driven Instrumentation and Applications with Soft X-rays*

Sharper and sharper experimental tools are often crucial for understanding of novel physical phenomena and making new discoveries. Today in condensed matter physics we are experiencing need for revolutionary new instrumentation for understanding interplay of many degrees of freedom interacting at different energy, length and time scales. These interactions lead to new phases of matter and emergent phenomena such as high temperature superconductors, topological insulators and two dimensional transition metal dichalchogenides, to name a few. The primary focus of my talk is to present some of the novel soft x-ray instrumentation developed during the last two decades at the Advanced Light Source and their science applications, through various examples for unraveling the emergent phenomena in quantum materials and energy related challenges. My talk will include advanced instrumentation for Angle-Resolved Photoemission Spectroscopy (ARPES), Ambient Pressure XPS and Resonant Inelastic X-ray Scattering (RIXS).
