| Research Abstract |
By means of polarization-dependent angle-resolved photoemission spectroscopy (ARPES), we examined how to evaluate magnitudes of many-body interactions on the quasiparticles near the Fermi level. We examined the Fermi surfaces and band dispersions selectively and determined coupling parameters of many-body interactions ofsingle crystalline metals (Pd, Fe, Mo, Al), Rare-earth metal thin films, ruthenate superconductors and iron-based superconductors.
