C34.00001: Making the invisible visible: Spins probed with soft x-rays Invited Speaker: Elke Arenholz The advancement of spintronics relies on our improved understanding spin based phenomena and our ability to engineer materials with specific magnetic and transport properties. In this talk, we will highlight the contributions optimized soft x-ray based characterization tools can make to this endeavour. |

C34.00002: Resonant Inelastic X-ray Scattering of Energy Materials: from Fundamental Understandings to Practical Developments Invited Speaker: Wanli Yang The pressing demand of improving the energy device performance calls for new concepts that require characterization techniques beyond conventional probes. With much improved throughput, ultra-high efficiency mapping of Resonant Inelastic X-ray Scattering (mRIXS) has opened up RIXS as such a powerful technique. This has become a timely and critical solution to characterize the novel electronic states of both transition-metals and oxygen involved in electrochemical devices, i.e., batteries, for energy applications. |

C34.00004: Laser ARPES on High Temperature Superconductors and Quantum Materials Invited Speaker: Xingjiang Zhou The mechanism of high temperature superconductivity in the copper-based and iron-based superconductors remains a prominent and challenging issue in condensed matter physics. Angle-resolved photoemission spectroscopy (ARPES), as a powerful technique to directly probe the electronic structure of materials, has played a key role in studying high temperature superconductors, as well as other quantum materials. In this talk, I will first briefly introduce ARPES technique, in particular, the latest development of vacuum-ultra-violet (VUV) laser-based ARPES systems [1]. Then I will highlight some ARPES results on topological materials including Bi2Se3 [2], monolayer silicene[3] and ZrTr5 [4]. Finally, I will report some of our recent results in utilizing the state-of-the-art laser-based ARPES to study high temperature cuprate superconductors [5-7] and iron-based superconductors [8-11]. |

C34.00005: Joseph F. Keithley Award For Advances in Measurement Science Talk: Science Driven Instrumentation and Applications with Soft X-rays Invited Speaker: Zahid Hussain 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). |
