Scope
Remarkable progress has been made in recent energy and momentum resolved spectroscopies in terms of experimental methodologies and resolutions, while the analyses have essentially been performed individually in each spectroscopy (for example, photoemission, scanning tunneling microscope, X-ray scattering, optical measurement, neutron scattering and so on). In this circumstance, directly measurable physical properties desired for theoretical understanding are limited. When different spectroscopic measurements are all combined further with ab initio calculations and/or data science approaches, it would lead to synergetic outcomes. Integrated analyses of momentum-energy resolved spectroscopic data are particularly important.
In this workshop, we first discuss recent progress on each spectroscopic challenge to strongly correlated electron physics from experimental and theoretical (computational) sides. We then encourage exchanging ideas and recent attempts for “integrated spectroscopy”, which can be reached, for instance, by the help of data science/machine learning with further help of the first principles computational physics to analyze spectroscopic data. Applications of the integrated spectroscopy scheme should cover frontier quantum matter fields and may include studies on mechanisms of strong coupling high-temperature superconductors including the copper oxides, and iron pnictides and chalcogenides as well as on the nature of novel quantum fluids and topological matter such as quantum spin liquids characterized by particle fractionalization and/or breakdown of particle description itself.
