Abstract 

The electron correlation effect gives rise to an abundant variety of physical properties of the d- and f-based materials. Among this class of materials, actinide compounds share a unique position due to their peculiar magnetic and superconducting properties. These distinctive physical properties are due to the strongly correlated U 5f states which exhibit both localized and itinerant natures. To understand the origin of these physical properties, the observation of their band structure and Fermi surface is essential. Angleresolved photoelectron spectroscopy is a powerful experimental technique by which the band structures and Fermi surface of materials can be observed. In this talk, I am going to discuss the electronic structures of strongly correlated uranium compounds studied by the photoelectron spectroscopy with soft x-ray synchrotron radiation from SPring-8 [1,2]. In particular, I am going to focus on the electronic structure of UTe2 [3,4].
